Have a C Arms Ridgeline w 375 rounds through it. Some handloads w 57.6 g Retumbo @ 2996 fps. Recently started showing pressure signs and hints of Carbon ring (had scratches on the bullets of loaded unfired cartridges). Did a good cleaning w C-4, then bore paste and the problem persisted. Christensen was helpful in my interactions w them and had me send it back. They put a new barrel on it at no charge and sent it back. Now the problem is worse. I started the barrel break in and only got through 4 rounds of factory Hornaday 143,s that chronod @ 2860 with Garmin Xero Pro (quite slow). Each round had progressively worse ejector marks and I could barely force the bolt up after round four. Any input would be helpful as I am not sure what to do next... I sure can't shoot it as is. Pics of chamber w and w/out cartridge below.
