Your welcome. Just passing in what I’ve seen on a couple forums. My buddy had a ppu 30-30 lock up his marlin 336. I was there, but not shooting it. He said it felt normal and I thought it sounded normal. We finally got the action open and the case looked normal. If you reload, it’s easy to remove the bullet and reduce the powder charge by 2-3 grains. If it’s loaded hot. If it’s loaded in soft brass, reducing the powder charge slightly will cause the brass to expand less to some degree and might cure the problem, or not. Not much you can do if this is the case. If you don’t reload, about the only thing you can do is swap it off. Less you find a reloading buddy to help. I’ve been seeing reports of others having problems with ppu in several chambering, some being hot loaded and some being softer brass that’s sticking. The softer brass was in 44 mag.
