Thread: Pressure issue resolved 7mm08

Interesting. Can you say approximately how many shots fired to get such a carbon build up? Was any particular ammo/powder mostly shot? Wanting to understand what goes into carbon building up. I have several older rifles from 30 to 80 yrs ago. Some of them with a fair mileage. Carbon ring has not ever been something of concern to me. Is it a particular issue for current "tight " spec chambers perhaps?
