[QUOTE="Bob Wright, post: 1685381, member: 104363"] Thanks for adding the sideviews. It was my son in law's 243 Win that had a carbon build up at the end of the neck. Of course, it would pinch that cartridge down with disastrous results, blew the primers and destroyed the cases, 2 in a row. The only soot on those cartridges was at the the outside chamfer of the case indicating that "pinch". Secondly, you have a obvious ring around the body shoulder junction as if excessive forming might be taking place, indicating headspace needs to be verified from unfired new, to fired cases. At least look at headspace and for carbon build up running the suppressor. You were asking why a suppressor causes excess carbon build up. Hot particles will attach to the colder material containing it, which is your chamber/bore. A suppressor gives the dirty hot gas more time to attach a greater amount of these hot particles. As far as why on some guns it doesn't foul up must be a component (powder, primer, neck tension) or a specific cartridge design issue that is an anomaly, like this. I have no suppressors to lend you that experience. [/QUOTE]
