I'm try to fix an issue with a recently acquired Dot 44 mismatch. When I first got it, I had difficulty cambering rounds. The bolt also was very stiff on closing. I replaced the firing pin spring with another one and that helped, but didn't eliminate the problem with rounds cambering. When I load 5 rounds, the top one will get jammed as the photo below shows. I took out the magazine floor plate and when looked at the spring it was compressed a lot, and the follower tilted downwards. I replaced it with a NOS one but surpisingly, that too had a downward tilt and still had issues cambering with a full 5 rounds. I replaced that one with another and this one had the follower sitting parallel which I thought would solve the issue, but it hasn't made a difference. The inside of the bolt and receiver are clean, no cosmo or grease. The inside of the magazine area doesn't show anything that would indicate any issues. I'm using PPU 196gr FMJ rounds.
When I load only 1 or 2 rounds, it chambers, but is still pretty stiff when closing the bolt. It feels like when I load 5 that the rounds internally are compressing inwards. Any ideas on what else the issue could be? I haven't tried other ammo since I don't have any but have used this PPU 8mm before in a Yugo K98 without issues. When I cycle the bolt empty it's smooth, the bolt handle does not have any resistance when closing.
