So I shot three new rifles today. First was a 30-06 Remington Long Range. Shooting the 178 AMAX with 59.4 grains of Superperformance powder and Federal 210 primers with Lapua brass. 5 rounds shot for an average 2862 fps. Blah. Not impressed. 5" group at 100 yards. Next five rounds will be loaded down to 58.0 grains and will stray from SAMMI specs of 3.220 COA to a .010 jump. Next up was a Remington Sendero II in 300 Win Mag. Also shooting the 178 AMAX with H4831 at 75.0 grains. Hornady brass and Federal GM 215 M primers. Average FPS was 2935 for a 1" MOA group. Blah. Next round will bump up to 75.5 grains of H4831 and will measure for a minimal jump instead of SAMMI 3.340. And the most disappointing next was a 350 Remington Magnum Ruger M77 MkII shooting 250 grain Hornady SP with 49.0 grains of IMR 4064. Federal 210 primers. Average FPS was 2125 and the group size was minute of pie plate at 100 yards. Switching to RL15 and going for 2300 FPS. The 250 grain bullets won't let me load to a minimal jump because of the mag box length so I may switch to the Hornady 200 grain SP bullet.
