    Test fired a gun I might purchase. My reloads using Cheddite primers were very close to being punctured. Are punctured primers a problem? How and why? Would shortening the firing pins 1/32 of an inch help?

    I would suggest shortening the firing pin .015 of an inch to start with. Then try it. I've done it myself and it works. A little at a time

    It is the Cheddite primers, not the firing pin. If you shorten the pins, you will more than likely end up short on the other shells with different primers on occasion.

    I understand options are limited right now, but just be aware of what the future may hold. Depending on the gun, changing pins may be more work.
