Brief range report of the first firing of the 460 G&A Win M-70. The rifle was built by Gene Simillion.

Started out with the original IMR-4064 loads developed by Tom Siatos. Fired Barnes 500 grain monolithic solids with 84.0 grains (MV = 2332 fps), 86.0 grains (MV = 2375 fps). I didn’t fire the 88.0 grain load having passed target MV of 2350 with the 86 grain load.

Also fired RL-15 loads with the 500 grain Barnes at 84.0 grains (MV = 2214 fps) and 88.0 grains (MV = 2256 fps). Will probably load 90 and 92 grains with the CEB BBW #13 500 grain monolithic solid for the next session as this is a slower powder than the 4064 and there’s sufficient room in the case without much compression.

Last batch was loaded with BL-(C)2 with the same 500 grain Barnes solid at 84.0 grains (MV = 2272 fps) and 88.0 grains (MV = 2343 fps). Will also load 89 grains with the CEB 500 grain solid for the next session.

All shooting was at 25 yds with peep sight and MVs are measured at about 10 yds uncorrected. This will be the second rifle for the Zim safari with the Ruger Hawkeye 458 WM described in the 458 thread and also fired today.

The rifle is very accurate, comfortable recoil - even seated at the bench - so I’ve decided to not add any weight as I had planned.
