Some odd things with the CCI primers
 

Some days ago i had tested some teflon taped thors, didnt work that well but heres the thing.

The fouling the CCI Inline MZL primers leave on the frame and breech plug is HARD. I actually had to use some wet steelwool and buff the residue off. I didnt leave the rifle for 3 days and i went to break the rifle open, the fouling on the frame stuck to the barrel LOL and it wouldnt open until i put some muscle into it.

The primers work awesome but as far as leaving it dirty for a couple days... its a BIG no no!

Why is the fouling from these primers so Hard?
