I have tried a number of hard cast 357 pistol bullets in my 35 Marlin. In every case, the bullet engages the rifling before the bolt is closed. I want to be able to shoot a 357 pistol bullet with a large metplate. I have tried a Lee crimper with mixed results. In some cases, the bullet had to be crimped on the tapered front portion of the bullets. This leads to reduced volumn for powder and the odd chance that recoil could make bullets slide farther into the case in the tube. An easier choice would be to relieve the rifling at the chamber. Can it be done? Have any of you tried relieving the rifling? If so, who did the work and how did you like it?
