I have a Mauser95 with it's 3rd barrel on it. It is a Sweedish stepped barrel 21" long.
I use 100gr hp Sierra bullet, 41gr IMR 3031 and 9.5 Rem primers. It shoots sub 1" groups at 100 yards. Ihave taken a woodchuck at 172 yards, lazered the distance. Shot clay pigions at 200 yards( not in the air ) The gun is a freak, it should not shoot the 100 grainers that good. We thought it would only shoot the 140-160 bullets!!! It also has a timney trigger, 3.5#.
