As we’ve previously noted, Midsouth Shooters Supply customers enjoy using Hodgdon powders, in part because the company makes great products, but also because the company’s experts supply plenty of help for shooters who want to get started in reloading.

We previously noted here that some of the company’s available materials appear in the Hodgdon Reloading Education section. Click here to see the landing page on which Hodgdon begins the education process. Click here to see Safety precautions. Then click the Reloading for Beginners tab to get an overview of the basics of handloading. This time, we want to probe more deeply into the data available for reloading rifle cartridges.

The Hodgdon Rifle Reloading Data page gets you started by asking you to select a cartridge from a pulldown menu. The lineup of available cartridges begins at the 17 Ackley Hornet and continues through the 50 Browning Machine Gun, or 50 BMG. What’s nice is there are dozens choices of currently available commercial favorites, such as the 30-06 Springfield, as well as popular wildcats (219 Wasp), new entries, such as the 28 Nosler, and proprietary rounds, such as the 240 Weatherby Magnum and others.

The Hodgdon Rifle Reloading Data page displays a pulldown menu with a lineup of available cartridges from 17 Ackley Hornet through 50 BMG. Magnum and others. Step 2 is selecting a bullet weight, then a powder manufacturer, then a specific powder.

Once you’ve selected a cartridge, which for our purposes here is the 25-06 Remington, you’re then able to select a range of bullet weights. In the case of the 25-06, that ranges from weights from 75 to 120 grains and a variety of bullet profiles.

When you select a bullet weight (or weights), the site returns a range of data for that load. Our search was to “select all,” which provided load data beginning with the 75-grain Hornady V-Max bullet. We then expanded that window and saw additional information about that choice, including Case: Remington, barrel twist (1:10”), primer (Remington 9 1/2, Large Rifle), barrel length (24 inches), and trim length for the case (2.484 inches).

Then, in more detail, the window for the 75-grain Hornady V-Max load lists the recommended powders, starting loads, and maximum loads, along with estimated pressure outcomes. The lowest-pressure starting load for the 25-06 75-grain Hornady V-Max round was with 58.0 grains of Hodgdon H1000, which will produce a velocity of 3,135 fps and develop 35,300 copper units of pressure (CUP).

The highest-pressure choice for the 25-06 75-grain Hornady V-Max round came with IMR 4451 (58.5 grains), which will produce 3,781 fps and 60,300 PSI (not CUP in this case).

Of course, you can deselect various elements to narrow your search. One particular bolt gun we have chambered in 25-06 Rem. has proven it can shoot commercial 115-grain Winchester Ballistic Tip ammunition (SBST2506) into three-quarters-inch groups if the shooter does his part, and its downrange performance with a 200-yard zero gives a bullet drop of -6.0 inches at 300 yards, so we can hold top of deer — but still on the target — and expect a center hit at 300 yards.

Unfortunately, that specific bullet isn’t available in the Hodgdon tables, but the data are still useful in building a test load to create something like it. We could select a similar bullet weight, such as the 117-grain Hornady SPBT, then look at which powders we wanted to work with to get the commercial round’s stated 3,060 fps muzzle velocity. (There are other considerations besides velocity of course, such as the bullets’ different ballistic coefficients, but first things first.) Or we could buy another 115-grain bullet, such as the Nosler Ballistic Tip, then use the 117-grain powder recommendations to begin working up profiles to build our own home-brew commercial load.

We’d choose one whose maximum load had a little velocity headroom in it — such as the Hodgdon Hybrid 100V that produces 3,111 fps with a maximum load of 50.5 grains and not the highest pressure. In this case, that’s 50,400 CUP. But there are plenty of other choices if that recipe doesn’t produce the results we wanted.

Also, you can narrow your selections by manufacturer or specific powder if you have already have pet loads you like to work with.

And that’s really the value of the Hodgdon rifle-cartridge reloading table: You’re able to select proven, safe, and varied mixtures of bullet weights and powder to begin making your own tack-driver loads.
