[QUOTE="live2huntmt, post: 1879521, member: 75903"] Update: I stripped the bore down to bare metal. Not sure about a carbon ring because I don’t have a borescope. Went to the range and fired 3 rounds to foul the clean barrel. Shot 3 more with 89.0gr of Retumbo and still showed over pressure and had the same velocity as before if 3147fps. I then shot 3 more of 89.0gr but seated .030” deeper, jumping.050”...showed slight pressure signs and produced 3122 fps. So I don’t think it was a copper fouling issue, and I don’t think I was seating into the lands. Next step, I am going to try different primers. I wish I could find a different lot of Retumbo to see if that would change anything. [/QUOTE]
