Attached photo shows a problem. It shot fine and no real recoil or lack of function. Noticed the broken case and that was only cartridge fired that trip to the range.
Other than maybe a gas seal, which should not be necessary at the pedestrian speed this was supposed to go, any suggestions on how to avoid this in future? If I have several more of these would they be safe to try if I start the bullets forward a little with the inertial hammer as if to pull them?
Brass is Winchester, not used more than three times. WLR primer. Unique powder nine grains. Bullet is .310 for 30/30, 170 grains from Oregon Cast. These worked earlier with eight grains Unique but were very slow, maybe 1200 fps or about the same as .22LR. This one was a little faster but not much.
