Home Forums Reloading Big Game Rifles IMR 3031 and the 260 Remington

So for some reason I decided to form some 260 brass from some Federal and PPU 308 brass I have laying around. The PPU brass was one pass through the 260 die and the Federal brass had to be run through a 7-08 die and then through a 260 die to keep it from collapsing at the shoulder. Of couse this had to be fireformed to my chamber so I loaded up the PPU brass with 90 gr. Speer TNT's and 35.0 grains if I3031. Accuracy is just fine with the newly formed brass and a very pleasant load to shoot it is. I ditched the bipod and shot off of couple different rests, every round fired would have dusted a Prairie dog out to 200 yards.
