Tech Report by Brian Williams
Reloading for a military surplus gun is different than loading for a modern precision rifle in my opinion. There are a few tasks that carry over from one to the other, but the main goal is slightly different. The target shot in the CMP games matches has a rather generous 10 ring, and with a little larger target your focus needs to change from a round with ultra accuracy to a round that is safe and functions well in your particular rifle.

Reloading for Vintage .30-06 Springfield Rifles

Brian Williams M1 Carbine CMP Modern Military 4-Gun 3-GunBullet Selection — With the .30-06 for my Garands and Springfields I stick mostly with 168gr bullets plus some 155-grainers. These bullet weights have just worked for me in the past.

Cartridge Brass (Milsurp vs. Commercial) — I use both military and commercial brass, having success with each. I do prefer commercial brass as it is easier to prep for the first reload. Military brass usually has a primer crimp of some kind that needs to be removed, and I have found that trimming these cases can sometimes leave you scratching your head as the OAL on military cases varies considerably.

My load has always been right around 47.0 grains, with both the 168gr and 155gr bullets. I also use the Auto-Trickler to drop all of my powder charges. This is a fantastic piece of equipment that not only gives super-consistent powder charges quickly, but it also makes one less thing that you have to worry about while on the firing line. With the Auto-Trickler, there is never a question about the powder charge in your ammo. As for primers, I have been shooting CCI 200 Large Rifle primers for many years and have never had an issue.

Case Care and Trimming — With most of the .30-06 brass that I use, I will only reload them 5 times maximum. I don’t push the brass too much, because the Garand’s semi-auto cycling can be tough on the cases. I also trim my cases for OAL each reload cycle. I use a Giraud power trimmer, so trimming is relatively quick and easy.

The chambers in some of the older rifles are not perfectly-machined like a modern high-end rifle. This can cause the brass to grow a little inconsistently, so I find trimming every load cycle helps to make sure that everything stays in a nice safe spec.

Case Annealing — A few years ago I started to anneal my .223 Rem service rifle brass. Now I have added that process for all my match ammunition. I anneal after every firing. It is a rather easy step as I can have my auto-feeding Annealeez machine running while doing something else, so annealing does not add a great deal of time or effort to the reloading process.

The .30-06 case was the father of the .308 Winchester, which was adopted as the 7.62×51 NATO cartridge.
