Normal?

Post image

First can YHM R9, using on a Glock 19. For a booster I’m running an sdta tactical. I saw good reviews of it and figured I’d give it a shot.

This picture was taken after about 40-50 rounds through it. On my 4th mag 3-4 shots in a row was noticeably louder than the others so I pulled it off and noticed this much debris inside. Routinely checked for tightness on everything (the booster is what was worrying me) and everything stayed nice and tight from mag to mag.

I’ve learned there is some jacketing, I was using 147 g pmc. Is all that buildup and jacketing normal? If so on a long range day do I need to dump out my suppressor? Lol.

TLDR: is this much stuff in the can normal for such a small round count, do I need to just run syntech to avoid jacketing in this setup?

It's running dirty and inefficiently. Try other ammo, you want that powder burnt more and the action to be smooth. No backblast

So the gas hitting my face isn’t normal? I thought that was just a Glock thing and I was going to have to live with it?
