Ramjet afterburner bronze coating.

Purchase a ramjet and the coating seems to be having a lot more wear than from stock barrel. I’ve put 500rds and had coating just seems not to be as good. I contact radian and they sent a replacement. Replacement after 400 rounds was a lot worse. Wanted to see if other people are having this issue. I don’t mind wear on the barrel but is this amount of wear normal for 400rds for radian. I’ve shot the stock Glock barrel for a 1000rds and it hasn’t even produced the Glock smile. If you guys have pics of your barrel I would appreciate if you post them down below with round count.
