A few things to check: Velocity, faster than normal?
OAL where bullets touch the lands, are the bullets seated so as to jam into the lands?
I noticed when I accidentally loaded a round meant for my AR grendel into my RAP that it was a lot harder to close the bolt. I full length resize everything grendel so you would think they would chamber fine in both firearms.
So if you are running brass in your RAP that had been fired in a different gun it may have some effect.
I switched to Lapua brass for the RAP and Hornady for the AR to make it easy to keep separate.
Last idea, My Rap's chamber is not very polished. I haven't had problems so I let it be. Something to check, a rough chamber makes it harder to extract.
