Re: reloading powder for 30-06
I shoot an M1 Garand so I load my 30-06 to the parameters of its gas system IMR 4064, IMR 4895, VV 135 and Varget are the powders that fit that rifle. I am a newer reloader, still testing for my final load, and made some changes in my process this time around that made any other data I had null and void.
I really like how the Hornady M1 30-06 loads shoot in both my M1 and my 1903. My research (based on one of their employees statements) indicates they load 46.5 of Varget under a 168 AMAX. These rounds loaded with Varget are the issue match ammo by CMP at Camp Perry. It is highly regarded by the shooters of mil surp cross course shooters as well as those shooting vintage sniper. Hornady loads to about 3.25 COAL for their ammo with the 168 AMAX. Buy a box of this ammo and give it a try to see if Varget is the way you want to go. You should be about 2700 FPS with this ammo.
I have had really good luck with 46.5 of IMR 4895 in my 1903 and it looks promising in my M1.
A friend gave me 10 rounds of 30-06 loaded with 56.5 grns of RL 19 that I fired through my 1903. It grouped better than anything else Ive ever shot so much so I doubted I was pulling the trigger.
I only shoot paper and use bullets that are terminal on paper only. Your requirements will need some more thought.
