Started today on the 44 Super Mag project. Some time ago I picked up a 44 Mag barrel for a Model 95 Mauser (currently in 308 Win) which was in very good condition. Initially I found that the bolt face would have to be opened up to accomodate the larger 44 Mag case head then I did some measuring and found that a shortened 308 case would fit the chamber without modifying the bolt face.
Trimmed to 1.450" it is almost 0.20"longer than the base 44Mag case. The extra length and the 1:22" ROT should allow this rifle to launch the heaviest 44 projectiles available. nya:
For the magazine I found the box for a M95 Spanish 9mm conversion which is a perfect length, just make a new follower and magazine spring. The action is already drilled and tapped for a scope mount so it will become a 4 shot scoped 44 Super Mag.
