“Segregation” is sorting and separating. If someone is looking for the best performance, which, in my mind, is the most consistent performance, from stock-on-hand, then it’s a worthwhile chore. However, it is a chore. Keeping that in mind, the item below hopes to help a handloader decide how to proceed when there are 100 new pieces of brass set out on the workbench.

I segregate new brass for my tournament rounds. The “tournament” is NRA High Power Rifle. That’s fired at 200, 300, 600 yards. Clearly, the “best” of my brass goes to the 600-yard-line. I do this with new brass because, as I said in an earlier installment, cases should be kept with the same load, and I want to know my best cases before I fire-form with my 600-yard load. Keep same for same.

The questions are: How many piles do you want? and What criteria do you use?

This is an old photo of my segregation results on 100 WW-brand .223 cases. These sized cases were checked using a runout indicator. Here’s how it broke down, left to right: 7 were “flatliners,” under 0.0005; 32 were under 0.0010; 37 were at 0.0010; 18 were up to 0.0015; 6 were over 0.0015; none were more than 0.0020. That’s pretty good, as far as I know. Seems good. I need a total of 88 rounds for a tournament, so I had confidence in this brass. Tip to make your sorting easy: Go to a discount store and get a few small containers, something suitable to contain several cases. Get some masking tape and write the criteria or content (after you sort enough to get a range) and mark the containers. Then just pitch each case into the suitable container as each is measured.

Get some masking tape and write the criteria or content (after you sort enough to get a range) and mark the containers. Then just pitch each case into the suitable container as each is measured.

In sorting cases, the finer the increments that define what you assess are Grade A, B, C (and possibly D, E, and F) cases, the greater the range encountered, and the fewer single examples that will occupy each group.

Establishing criteria limits (defining the contents of each pile) comes mostly from experience in checking examples of the stock. One thing you will learn from segregation is what the component is “supposed to be.” You’ll see a pattern. The more you measure, the more you’ll learn, and it will help to establish the criteria you end up banking on.

For me, I sort by wall-thickness variation, specifically, case-neck-wall-thickness variation. All other things being the same, and the tooling being what it should be, consistent case-neck walls result in bullets looking into the dead center of the rifle bore. Some call it “concentric,” and I do too.

You’ll need either an “inside” micrometer (which has a ball-end, made for tubing measurement) or, way faster and easier, a specialty fixture that incorporates a dial indicator. The micrometer will be more precise because it will provide a number in the 0.0001’s, but that gets back to the realism of the criteria. A quality dial indicator still shows less than 0.0010 variations, just look at the needle position between whole marks. Measure at 4 points around the neck. My expectation is “0” for my 600-yard brass: no variation, which really means I accept anything that’s under 0.0010. I end up with piles in 0.0005 increments: less than 0.0010, 0.0010, 0.0015, 0.0020, and any larger doesn’t get fired in competition. I do this because it’s direct and fast, and because I am looking for good, better, and best case groupings to coincide with my needs for 200, 300, and 600 yards.

This appliance is from Forster and is pretty versatile. Purpose-built, single-station tools are a little better to use, but, all around, something like this serves most well.
This appliance is from Forster and is pretty versatile. Purpose-built, single-station tools are a little better to use, but, all around, something like this serves most well.
Here’s how to use the tool to check wall thickness. Zero the indicator against the pilot/spindle and then read the dial with the case neck over the spindle; position the indicator about halfway down the neck. I read it at 12, 3, 6, 9 on the clock face. Understand that wall thickness variation and runout are related, but not directly.

I read it at 12, 3, 6, 9 on the clock face. Understand that wall thickness variation and runout are related, but not directly.

If I get lazy, which is more common now than not, I size all the cases (to get the necks shaped up) and then check runout at the neck on another specialty tool: a concentricity fixture (some call it a “spinner”). The system I’ve been using here of late serves both duties. Make sure to have run some sort of inside-neck sizing appliance, either an expander in the sizing die or a mandrel after the fact. If not, the results will not be viable. This explanation isn’t too detailed, but the variations get “pushed” either inside or outside depending on the last tooling the case neck was treated to, and it needs to be pushed to the outside.

Does it really matter? Yes. There have been tests done by many trying to establish the point where wall variations or runout influenced group size. Since this point varies in different tests I’ve seen, I have to believe that the rifle/ammo combo has a mighty influence. It’s very likely that the better the package, the more sensitive it will be to showing up variations. I do know that when Hornady tested this at 200 yards (on their indoor range), they found that variation in wall thickness of 13% had a significant influence on group sizes; in this instance, that equated to about 0.0015 inches variation.

Reposition the hardware to check runout. This is not as precise as measuring thickness, but, in another way to look at it, provides more of a “what you get” evaluation. A 0.001 wall variance does not directly equal 0.001 measured runout. The basics of segregation: you can only find what you’re looking for. One tip: I get my most consistent, most accurate results by lifting and re-seating the indicator at each point I want to check rather than actually spinning the case and watching the indicator needle movement. It’s easy to check loaded rounds too, as shown. There’s a good deal of wobble in many factory loads, and if you rely on it for important shots (like on a big hunting trip) sometimes it’s good to know that you have the best-of-the-box in your pocket.

There is another popular and viable means of segregation and I’ll work that one next time. How you choose to segregate brass does have something to do with what the ammo is ultimately used for.

 

Midsouth Shooters Crawfish Cup Part 2: Shooters Ready!

Facebooktwittergoogle_pluspinterestyoutube

Many of our readers are reloaders. It takes a different mentality to submerse one’s self into creating something to be used or consumed. Farmers get it. Butchers understand. Carpenters, masons, builders, creators, doers all understand. When one works for something, and sees the fruits of their labor, they gain a level of respect beyond the intended use of their creation. Although we weren’t competing, we were allowed to get a glimpse of the work that goes into becoming a competitor in action pistol, and the be a participant in The Crawfish Cup.

Friday, the practice ramped up, especially on the new mover. Shots rang out across the range from Tracie and Eli Rushing as they took on each station. First Timer at The Crawfish Cup, Tony Holmes greeted us with a smile, and many kind words, and set to work preparing himself for the match to come. It was amazing to see these titans of the sport, Doug Koenig, Bruce Piatt, Kevin Angstadt, and Tony Holmes gather together across a few tailgates, and not only discuss the course of fire, but rib each other like old friends.

Soon after, the laughter died away, and the calm of experience took over as each shooter set off for his or her area of desired challenge. It was at this point we saw where the training ethics play a major roll in action pistol. To even be able to hit these targets, whether they’re turning, zipping from side to side, or just falling down after they’re shot, is a feat. Being able to maintain the amount of X’s (shots in the bullseye location) each competitor racked up was astounding. We tried! We were invited to try the falling plates at 10 yards. No big deal, right?

It’s harder than it looks, and it should be. It takes work, training, and dedication. Furthermore, it takes discipline! To develop a level of control where one removes their own body as a variable, is what separates a professional from the rest of the lot.

 

The feeling of community pervaded the entire day, especially at dinner. We gathered at Big Daddy’s, a local fixture in Lake Charles. Shooters of all levels, old hands and new faces alike, gathered like family to demolish mud bugs, and discuss the competition ahead. The food, much like the company, was fantastic. Saturday loomed close, and in order for a nice crop of X’s to be harvested, the fun had to slip behind the barricade, and the work had to begin.

Midsouth Shooters Crawfish Cup Part 1: Welcome to Lake Charles!

Facebooktwittergoogle_pluspinterestyoutube

2016 marks our first venture into action pistol, and it was an amazing experience, filled with great people. Action pistol is a sport, in every sense of the word. It takes a ridiculous amount of dedication, discipline, and attention in order to be a competitor.

Our group arrived in Lake Charles, LA to a torrential downpour. Thankfully, the clouds parted shortly after our arrival. In 2015, the competition, as well as the competitors, weren’t so lucky…

This year was blessedly cooperative weather-wise. The wide field of 87 competitors, ranging in all ages, and pistol varieties, were eager to get their feet wet on the course of fire, so to speak. Greeted by the range master, as well as the lead range officer, George Mowbray, and Gary Yantis, the heart and soul of the match. Their experience and expertise are only matched by their hospitality, and their willingness to impart any knowledge one wishes to gain about anything Crawfish Cup.

Gary and George, both pro pistol shooters with decades of experience between them, have built an amazing match thus far. In 2015, the match saw 70 competitors, with Bruce Piatt taking home the cup. 2014 had a similar field of competitors, with the Midsouth sponsored shooter, Kevin Angstadt raising the cup. 2013 had world class shooter Doug Koenig adding the Crawfish Cup to his trophy case. Every year saw outstanding competitors, and George and Gary making sure every competitor had a safe, fair, and fun competition. Having them to work with in preparation for 2017 only fuels our desire to exceed the progress we made this year in providing the best experience for every competitor on the road to the prestigious Bianchi Cup.

Something that makes the Crawfish Cup special is the field of competition. We had the immense pleasure of meeting great people at every turn. Please head over to the competitor profile section to meet a few shooters from all over the U.S. Each one brought something special to the match. Also attending this year were the three members of the Yackley 5ive, Tim and Sean Yackley, and their mom, competitor Becky Yackley. These bright young men are the future of action pistol. We got the chance to bounce a few questions off them prior to the match:

Tim, Sean, and Becky Yackley
Meet Tim and Sean Yackley, and their mother, Becky Yackley.

Tim and Sean Yackley are not only involved in every aspect of action pistol, they take their dedication beyond Crawfish and Bianchi Cup, and into long range shooting, 3-gun, all the way down to working the reloading bench. When asked about their level of commitment to the shooting sports, they said, “One of the things that really makes us love shooting is seeing what we’ve been able to do with all the little things we’ve done:  we don’t have anyone training us, it’s a lot of our own work, over years.  As kids, it’s neat to see the tiny bits of work we do with each other turn into a great performance – stuff like working on particular skills and seeing that help each other in a match, or taking a small piece of advice someone gave us on say, shooting barricades, and seeing it play a role in something we figure out and can grow from – those things really make the little parts of everything we’ve done, with help from lots of people come into play.”

These Lucas Oil Outdoor sponsored shooters are already making a name for themselves. Tim Yackley took home first place in the Master Category, at age 13! Proof positive of a stellar career in shooting sports, and a definite presence at The Crawfish Cup.

Team Cerino stands out, and it’s not just because of Michelle’s tiara. Chris and Michelle are fierce competitors, and have a great rapport with every other shooter they encounter, adding a level of fun to each section of the match that we had no idea could exist in such a regimented structure.

Vera Koo is not only a shooter of legend, she’s a true ambassador to the sport. Earning High Lady, and Grand High Lady this year at the cup was a great achievement. Beyond that, she donated $300 of her own money to be divided up, and given as door prizes to other shooters.

Ten Essential Tips for CCW Holders

Facebooktwittergoogle_pluspinterestyoutube

10-CCW-Tips_Page_01Beretta’s free e-book, Ten Essential Tips for CCW Holders, has some useful tips to consider, in particular for gunowners who are contemplating the pros and cons of everyday carry for themselves.

As the Beretta CCW booklet says, “Carrying a concealed handgun requires a certain amount of confidence. You need to be confident in your knowledge of laws and regulations. You have to have confidence in your accuracy, and you need to trust that you can carry a gun effectively, securely and comfortably. If a gun is a burden for you to carry, you probably won’t.” So far, so good.

Click here to download 10 Essential Tips for CCW Holders as a PDF.

The topics covered are:

  1. Introduction
  2. Knowing How to Carry Your Gun Comfortably and Effectively
  3. Dressing to Keep Your Weapon a Secret
  4. Understand Your Weapon’s Capabilities
  5. Choose a Suitable Caliber
  6. Practicing Basic Skills
  7. Try Your Hand at Point Shooting
  8. Training to Clear Your Weapon
  9. Stage Your Weapon
  10. Closing to Engage a Threat

And Beretta offers some additional information which may be of value to our customers who are considering making the move to concealed carry:

  • 55% of gunfights take place 0-5 feet.
  • 20% of gunfights take place in 5-10 feet.
  • 20% of gunfights take place in 10-21 feet.
  • 95% of gunfights take place in 0-21 feet. (Source: FBI)
  • The average man can cover 21 feet of ground in 1.5 seconds.
  • The average man cannot draw a gun from concealment in under 2 seconds.
  • The average gunfight is over in 3-5 seconds.
  • 3 to 4 shots are usually fired.
  • Most gunfights take place in low-light conditions.
  • On average, one shot in four strikes someone.

Here are three of the ten tips in more detail:

Dressing to Keep Your Weapon a Secret

Once you’ve chosen a holster and a gun, you have to hide them both. The trick is keeping the gun both concealed and accessible. The main give-away is the gun’s outline being visible through clothing (printing). Some tips on choosing the right clothing to carry concealed:

  • Wear pants that have enough room in the pocket or in the waist band to comfortably carry the gun.
  • Shirt tails provide good coverage. Wear shirts that are meant to be worn untucked, and make sure your shirt extends past your waistband.
  • If you will be wearing shorts and T-shirts, you will have to consider carrying a small gun. A slim gun in an IWB holster should easily be covered by a shirt.
  • In fall and winter, heavy clothing will allow the concealment of even full sized handguns.
  • Suit jackets and coats make concealment easy.

Choose a Suitable Caliber

Here the rules are easy to understand. Larger rounds require larger guns, and typically do more damage. Small-framed handguns with short grips can be difficult to grasp. But larger guns are harder to conceal. Again, there is a balance that must be considered.

  • The .25 ACP is a tiny round that is fired from tiny guns. While easily concealed, the .25 ACP is not known for its stopping power.
  • The .32 ACP is moderately larger, and can be a perfectly effective round (though most consider a .32 to be a backup for a larger gun).
  • The .380 ACP is a very popular choice. The .380’s recoil is manageable, which allows for more accurate repeat shots. And many ammunition manufacturers make excellent .380 defensive rounds.
  • The 9mm is very popular, and close to the upper limit for lightweight concealed carry.
  • The .40 S&W is slightly larger, still. It is a popular choice for many law enforcement agencies.
  • The .45 ACP is a venerable handgun round, and offers excellent stopping power, though it is a bit slower than the 9mm.
  • The 10mm is seen by many as the upper limit of practicality. It is a .40-caliber bullet backed by more powder.

Many feel like the debate over caliber misses the mark. Practice, skill, and accuracy will do more for your success than a big bullet. Look for a gun that’s easily concealed in a caliber you can confidently handle and work on your shot placement.

Training to Clear Your Weapon of a Malfunction

What can go wrong will go wrong, and that applies to handguns as well. Sometimes primers don’t ignite the powder. Or the bullet will fire, but the gun won’t extract the spent brass. Or the next round won’t feed quite right. Anytime this happens, you have to fix the problem. Try a tap-rack. Pull the slide back with your non-dominant hand, hard, and let it go again, like you would if you were chambering a round. Sometimes a little shake will free a loose piece of brass. When the slide falls, it usually picks up the next round, or may push a stuck round into place.

This is easily practiced. Snap-caps and/or dummy rounds will allow you to simulate these problems without live rounds in the gun. See how easy (or hard) jams are to clear, and how quickly you can do it. Keep practicing these drills until the tap-rack becomes second nature.

In the worst case scenarios, you will need to lock the slide back and drop the magazine in order to clear the issue. Practice this, too. Your life may depend on your ability to understand the problem and fix it quickly.

When you decided to begin daily carry, what was the biggest obstacle for you personally to overcome? Let us hear your thoughts in the comments section below:

Iowa Legalizes Suppressors; Free Shoot Set for April 16

Facebooktwittergoogle_pluspinterestyoutube

ASA-Map-March-31-2016

Iowa became the 42nd state to legalize suppressors when House File 2279, introduced by Rep. Matt Windschitl and Rep. Terry Baxter, was signed by Governor Terry Branstad on March 31. And to celebrate, a national suppressor-owners’ rights organization is throwing a free shoot next week.

After three years of efforts by the American Suppressor Association (ASA) and the Iowa Firearms Coalition (IFC) to educate lawmakers on the benefits and realities of suppressors, HF 2279 was met with positive response. The legislation passed earlier this session 46-4 in the Senate and 78-21 in the House.

Effective immediately, the new lawalso makes Iowa the 39th state to allow for the use of suppressors while hunting.

“The legalization of suppressors in Iowa is a tremendous victory for the law abiding citizens of The Hawkeye State,” said Knox Williams, President and Executive Director of the American Suppressor Association. “For the past three years, the ASA has worked alongside the Iowa Firearms Coalition, the National Rifle Association, Rep. Windschitl, and, this year, Rep. Baxter to get this legislation passed so that the sportsmen and women of Iowa could use these benign accessories to protect their hearing while in the field and at the range. We are incredibly excited that Iowa is now one of 42 states that allows suppressor ownership, and one of 39 states that allows their use while hunting.”

To celebrate the new law, the American Suppressor Association will be hosting a public suppressor shoot from 10 a.m. to 1 p.m. on April 16 at the Big Springs Shooting Complex.

To find the range, use Google Maps and search for the address, 5015 Highway 146, Searsboro, IA 50242. That will get you a pointer right by the range gate, according to the Big Springs Range website.

Knox said, “We will be bringing the top manufacturers from across the country to showcase their products, and educate any interested Iowans on why they should be excited that Iowa became the 42nd state to legalize suppressors. Admission and ammo are free, so we encourage you to join us!”

How to Use MOA and Mils to Become a Better Shooter

Facebooktwittergoogle_pluspinterestyoutube

Several Midsouth Shooters Supply customers have asked for explanations of minute of angle and the measurement term “milliradian” (mil) and how to use a mil-dot scope to measure the distance to your target at the range and in the field. In the accompanying two videos, the National Shooting Sports Foundation’s Ryan Cleckner explains both concepts and how to put them to best use.

Looking for more long range shooting instruction? Cleckner’s book, Long Range Shooting Handbook, is the complete beginner’s guide to long-range shooting written in simple every-day language so that it’s easy to follow. Included are personal tips and best advice from his years of special operations sniper schooling and experience, and as a sniper instructor. If you are an experienced shooter, this guide will help you brush up on the principles and theory of long-range shooting.
