A cure for this would be to use a harder alloy as we would for hotter cartridges but this creates problems. First its too much strain on the loading lever so a bench press would be less damaging to the gun. Second if you have a mishap and have to draw the ball it wont be as easy to screw an extractor in.

Alternatively reduce the strain and use thicker wads. Or stick to light loads. Or go back to balls as John says.
where can i get a bench press
