    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.

    I agree with Stl Flyn, I purchased some Cheddites to shoot in my 1100 this fall and winter, the first 900 shells no pierced primers, the last 100 shells had more than 20 pierced primers. I get 3 to 4 pierced Cheddite primers per 100 with my K80, I stopped shooting them after 200.

    I will shoot the Cheddites in my 1100.

    I have used over 40,000 cheddites, in multiple guns. Never had a punctured primer.

    I agree with mission 622 have shot close to 20,000 reloads with cheddite primers in my K-80 and no punctured primers.

    What gun are you looking at? If it is a browning -no problem $15.00 firing pin, 15-minute job to change, shorten it up - If it is a Caesar Guerini that doesn't sell parts, but have to send it in if it doesn't work, might be a different story.
