I have a pair of 9.3x57 rifles. The scoped one is based on a M98 action and the barrel is so bad I would not want to shoot cast bullets in it, but the M96 one has an excellent barrel.
A CGN member sold me 200 commercially made 275 gr cast bullets. I loaded these with a test of 25, 30, 35 & 40 gr of a military powder similar to 3031. The 25 and 30 gr shot very well. The 35 gr shot 3.3" and the 40gr shot 4.1"
50 yards - Iron sights
