Glen Zediker

First, I thank you all for responding as well as you have to this little series. I appreciate the kind comments. I know that there are many eager for me to get back to the fine points, the advanced measures, but I also hope reflecting on what I taught my son likewise has caused some pause for reflection in your own processes.

Although it may be back with other installments as things progress, I’ll finish this little series for now by going over a few process particulars that, in part, my son had more difficulty getting the hang of and, also, those that I think are absolutely mandatory to teach and coach to a new handloader, especially in creating ammo for a semi-automatic centerfire.

Case Lube
Learning how much is too much and how little is too little is an easier step if you’re using a high-quality, high-performance case lube. I know from past experience addressing this topic in Reloaders Corner that we have differing opinions amongst the readership as to the best formulation for this essential step. For me it’s always been one of the “rub-on” lubes, like Redding’s Imperial Sizing Die Wax or Forster Case Sizing Lube. I like the control, speed, and ease of die operation those products give me. However! I will freely and quickly also tell you that a lube applied using a roll-over type pad or spray delivery takes a lot of the “feel” out of this process, and that’s not always a bad thing.

learning to reload
There’s different products and ways and means to apply case lube. No matter what or which you choose, it takes some trial and error to learn how much to apply.

The rub-ons are so slick feeling that it’s tempting to use too little. I treat each case with a fresh dab. Charlie figured out that really wasn’t necessary, that he could go two or three without having to reup and reapply the lube to his fingers. These lubes continue to indicate, based on feel, that there’s an adequate coating, until he dang near almost stuck a case. He was correct, at least one more use per reload was possible, but there’s a measure of consistency in starting the same with each case prior to sizing. I pointed out that there was no harm done in a more ample coating because it was coming back off anyway. And then, of course, he asked about the pressure-induced dimples he was getting from using too much of it! Right: one extreme to the other. There’s a feel to this process, but it’s a balance pretty easily managed — as long as you’re not trying to see how little case lube you can get away with.

Sizing Die Set
The first on the list of “always” was learning to set the sizing die to accept those lubed cases. I mentioned this briefly before, but I am absolutely adamant about using a cartridge case headspace gage to adust the amount of sizing each case gets. I’m talking about case shoulder set back. I did a piece some time ago here about the challenge of loading the “same” ammo for use in different rifles, which are near about certain to have at least slight variations in chamber headspace. Compromise has to favor the gun that needs the most shoulder set back, and we hope there’s not a huge difference across the rack of rifles we’re using this ammo in.

learning to reload
This tool is a great investment and strongly recommended: Hornady LNL headspace gage. It’s how to set a sizing die for maximum utility and minimum case stress.

I promise it was not due to any sort of parental retaliation for misdeeds in the past, but I let Charlie start off with a brand new disassembled sizing die.

Setting set back is a tedious process that requires numerous checks. We use a Hornady LNL gage. We measured a few different spent cases from a few different rifles and, fortunately, didn’t have much variation (about 0.002). We took cases from the shortest chamber and set them back 0.004, which is what I usually recommend, and accepting that meant some were getting pushed a little more than ideal, but all were still well (well) away from the maximum the sizing die would give. That’s where the die is sitting now. I don’t recommend cutting it too close for reuse in something like an AR15. I won’t launch into a detailed look into either of those single topic-points, but following the die setup instructions that come with most sizing dies will result in what I say is excessive set back. So even a compromise still meant we were getting the least amount of brass working in sizing, and (mostly) ensuring safe and reliable function. We started with once-fired cases all from the same ammo lot, by the way.

Priming Ain’t Easy
Once again, this topic has been addressed here by me a few different times and ways in these pages, but teaching someone how to correctly, and safely, set and seat primers is best done with a “hand tool.” It doesn’t have to be a zoot-capri benchrest specialty item, but, well, to make a long story short: using the bench-mounted tools I had on hand (and trying three different ones) Charlie was retrieving and retaining essentially none of the finesse I was trying my best to explain — “Feel the primer come to a stop on the bottom of the pocket and then compress the anvil…” And it’s even harder using a press-mounted device. With anything (that I’ve used) besides a hand tool there’s too much leverage over too short a stroke to feel the progress and end of a well seated primer.

Learning to seat primers correctly is key, and something like this will teach you all you need to know about that process. This Lee-brand hand tool is not expensive but it honestly seats primers as well as anything I’ve yet used. There’s an overage of leverage in other style tools and that precludes developing the feel necessary to ensure consistent success.

We’re not nearly shooting Benchrest, but for the sake of consistent ammo performance and safety all primers should be seated well, which is to say well-seated. And, especially for a semi-auto, they all must be seated to below flush with the case head.

I handed him said hand tool and after a scant half dozen experiences, he had it down pat. A serious light went on and smile appeared: Oh! Moving then to bench-mounted tool he had learned what he needed to know, or had felt what he needed to feel, and instinctively slowed down and lightened up and got the same good results. The lesson here is that if you’ve never used a low-leverage hand-operated priming tool, try one. You might not want to stay with it, especially when faced with the small mountain of brass such as we collect for processing, but it will teach a thing or three.

One not so minor point we all have to learn, and definitely don’t want this one to be learned the hard way, is taking care when using primer feeds (trays and tubes).

Suitable Seating
The last thing on my list of “things that stood out” in this process of teaching Charlie to reload was setting up the bullet seater.

Another valuable gage is one that gives a way to know at which cartridge overall length the bullet touches the lands or rifling. Do not assume that because it fits into the magazine box that it’s good to go!

With an AR15, or any rifle with a detachable box magazine, the clear overall cartridge length limit is defined by what will fit into the box. There’s more to it than that. Different bullets have differnent profiles and ogive dimensions. This influences how far from the lands or rifling the first point of bullet major diameter (that which coincides with land diameter) will be when the round is chambered. I recently wrote about having some “sticking bullets” in a rifle. This was a factory load but the bullet profile, overall cartridge length combination exceeded clearance — the bullets were jammed into the lands. Not what you want, unless of course you know what’s what you want (and that’s another topic entirely).

A fair number of .224-caliber bullets may touch the lands if seated to an overall cartridge length that fits the magazine box, if that’s the only criteria used to determine round length. These have to be seated more deeply, resulting, of course, in a shorter overall round length.

Never (ever) assume! Mil-spec, and most other, .223 Rem. rounds, for instance, will have the ballpark 2.250 inch length (in my notes the max is 2.260) that closely but adequately clears the box walls, but some I’ve used have to be down a good 0.025 under that to avoid sticking the bullet into the lands. I’ve seen this be most prevalent in lighter weight varmint-style bullets. Check it to make sure. And, as long as there is a gap between the bullet and the lands, all is fine.

The tool to use is a Hornady LNL OAL Gage. Once again, the only measuring tool needed for use with either of the gages mentioned is a decent caliper.

  1. Good overview of more basics, thanks. I always learn something, even if it’s a small detail. I agree on the hand case lube. Seems everyone likes the Imperial, and it’s excellent, but my favorite is the similar Hornady Unique. Works great and the small tub lasts forever. I just need a faster system to lube inside the case mouth, which is tedious.

    I’ve tried the Lee hand primer which does have a good feel, and have the bench mounted Lee auto-prime which is even more stable, but the RCBS APS Hand primer that uses the strips works best for me, and is very good quality. I can buy the primers on strips, but can also load them onto empty strips with the RCBS strip loading tool.

    1. Thanks for your insights and service to our community. I have some of your books, and plan to get more.
      As far as lube, I like to use a 1/20 mix of anhydrous lanolin/99% isopropyl alcohol.
      Mix up a batch and put in an airtight container (alcohol will absorb water from the air). Put a few drops in a baggie with your brass. Seal, shake, and size. Can be used wet or let the carrier evaporate. Most effective, least messy lube I’ve used (I’ve tried the ones you mentioned and others) and the least expensive to boot!!

      1. I use the 1/14-20 mix and spray a couple rows of cases laid out. Roll them over and spray again. let dry a while. Size the cases then put some in a quart drink cup and pour some acetone on them. Pour back and forth to another cup letting acetone pour over them. Back and forth 5 times or so. then pour into a cup with holes in the bottom back and forth to drain. let dry hour or more then load away. My loads with cheap bullets average 1 inch group at 100 yards. Still trying to get on 200 and 300 yard range. Like to find a 500 yard range.

    2. If your sizing die is a RCBS or Lyman you can purchase a carbide expander/decapping die from Lyman that fits both brands and skip lubing the inside of the case mouth. As far as priming goes, find a first generation Hornady hand held priming tool and never look back. You can search Ebay and gun shows for same.

  2. Being new to reloading, I appreciate the basics because it helps to verify what I read in “hand loading for competition”. My very first full length resize was a full length stuck! I’m glad it happened that way because learning from experience is the best and it will never happen again ; ) If it weren’t for that book, I would have given up on my CZ 527 (.223) and put it up for sale. The only factory ammo that would shoot under 2 MOA was Federal law enforcement with Nosler ballistic tips and they’re not cheap. My very first 5 rounds of reloads (after the stuck case-Ha) using all of Glens info netted me a 0.8 five shot group. The OAL gage I think has been the most invaluable tool to help me achieve those numbers (and better since). I found that factory ammo had to jump across the Grand Canyon before it hit the lands of my barrel. There must be something wrong with me because I think I enjoy reloading more than shooting! Thank you again Glen for all your knowledge and for making reloading fun.

  3. I have a bit of a problem with your advice re priming. I’ve been reloading since the very early 1970s and frankly found all the advice from mfrs who produced reloading tools to be in error not only regarding priming, but also how to set-up your sizing dies,
    whether standard cases or belted magnums. But to stay on topic,
    lets discuss priming. Long ago I discarded info on “how to lubricate” your brass as you resize said brass in the sizing die.
    I grew tired of sticky fingers (RCBS Lube using their pad), along
    with excessive or not enough lube! About 45 yrs ago I switched
    to using wax, Specifically, Redding Imperial Sizing Die Wax. And it has worked out very well: no longer have to worry about contamination of bullet or powder (easily wipes off hand with a paper towel).
    Re priming: I also STOPPED using the auto primer on my presses and went to tools designed for hand-priming. Result:
    No more misfires, or any other concerns. Because I was using tools designed for hand-priming, you could “feel” the primer seated in the case head. You could also “feel” the primer that didn’t seat easily on new brass. Hand priming was my solution to all the mfr’s nonsense instructions re priming.
    Ironically, using a Dillon Progressive Press, I found all the instructions from Dillon to be accurate, and subsequently used their recommendations using their progressive presses to load
    thousands of 45 ACP ammunition. Ammunition that greatly improved my competitive scores back in the late 1980s.

  4. So, I’m still a novice for sure. Only reloading for about a year. Maybe 15,000 rounds total across 5 calibers.
    I use basic RCBS case lube cut with some 91% PrOH . For .223 I lube every other case. I drop a large drop of lube on the pad and dip or sort of “gouge” every 5th case mouth into it to lube the expander.
    For priming, I really like the RCBS ram primer on the press. I like the hard stop and being able to adjust the depth. I understand the writer and the soft touch feel for priming, but I don’t have an issue feeling the primer on the press . Just have to use a couple fingers until it’s set right.
    I have yet to really get in to the super fine adjustments for seating depth and setback… better accuracy and consistency is always better, but I am still working at 200m or less. Not there yet. All good info though, I really appreciate learning.
