After shooting some 25 rounds thru the CZ hornet, I have been examining the fired cases. It is not apparent, even under a magnifyer, that the cases have been fired. I have read that CZ uses the Hammer Forged method to make their riflings along with the chamber. This is, as I understand done in a single process.

I have also used some sweets in the barrel, without any signs of copper retention. It really seems different that after 25 rounds, the barrel has no apparent copper build up.

Would any of you care to speculate or give us your experience with these barrels?

My CZ American 221FireBall is loaded very near the top & it doesn't copper foul hardly at all either. As I understand it there barrels are hand lapped. If I'm wrong please tell me.
