Doing a little test. Last hunting season I worked up a load in 9.3x74R with new Hornady brass, R-P 9 1/2 primers, PPU 285gr RN, and a healthy dose of H4350. The load shot 1/2” groups at 100 yards and velocity was 2325fps. This morning I loaded that same load except instead of new Hornady brass I used once fired ( not by me or my rifle ) FL sized S&B brass. I’m looking to see what effect the change in brass has on accuracy and velocity in this rifle.



32 Winchester Special and 30-40 Krag are there for scale.
