Ammo Paradigms: Accuracy vs. Speed vs. Temp Stability

USAMU Reloading tips Handloading Hump Day

This article, in longer form, appears on the USAMU Facebook page, as part of the “Handloading Hump Day Series”. This article explores three different “Philosophies” of precision reloading. Some handloaders seek to produce ammo that yields the very tightest groups (without factoring in the wind). Other shooters load their ammo to deliver the highest safe velocity. That’s because a projectile launched at higher velocity will drift less in the wind. The theory is that even if fast ammo doesn’t produce the tightest groups in zero wind conditions, it will yield higher scores in a the real world (where the wind blows). Lastly, some handloaders favor ammo that is ultra-consistent across a wide temperature range. This last philosophy dictates selection of a powder that is temp-insensitive, even if it may not produce the very best raw accuracy (or speed).

What’s Your Handloading Philosophy?

Objectives of Reloading — Accuracy, Velocity, Temp Stability
What do you, the reader, primarily value in your handloads?

Viewpoint ONE: Accuracy Trumps Everything
Some shooters prize consistent, excellent medium/long range accuracy enough that they’re willing to give up some extra velocity (and reduced wind deflection) to obtain that. Their underlying philosophy could be stated: “Superior accuracy is present for every shot, but the wind isn’t”. One’s ability to hold well, aim well and read the wind are all factors in making this type decision. The photo below shows stellar raw accuracy. This is an 0.67″, 10-shot group at 300-yards fired from a text fixture. The group measures just 0.67″. (This shows the USAMU’s 600-yard load with 75gr bullets).

Get 3-Gun Fit with Anette Wachter

Anette Wachter (aka ’30CalGal’) is one of America’s top long-range sling shooters. A member of the U.S. National Rifle Team and a NRA High Master (both mid- and long-range), Anette has an impressive shooting resume. She has also recently started shooting 3-Gun and tactical matches. These “run and gun” matches involve rapid transitions, with shooting from a wide variety of positions. To help improve her 3-Gun shooting, Anette has developed a specific exercise regimen, which she calls the 3-Gun Biceps Series. Here’s a short sample:

ANETTE: One thing you can be sure of in a 3-Gun match is shooting from weird positions. I have noticed that the stage designers love port holes [in barriers]. There are many that are on the ground that you have to shoot through. Or perhaps it is not a port hole but just underneath a barrier. Imagine you are running to that spot with rifle in hand and you have to use one arm to brace your fall to the ground, while holding the rifle safely and facing down range in the other, and then get in to position to shoot, then back up again using one arm to push off of. I have an exercise I have been doing for a awhile that works great for this move…

The “Shooting Low Porthole Plank” starts off in a plank position — make sure your back is straight.
