I checked the magazine, since the bottom cover of the mag contains the spring which is a heavy duty leaf spring, its impossible to install it rearwards, same with the follower.
I think I have identified the problem, the bolt wobbles enough to miss the rim of the cartridge during feeding, the rim of th round slips off the bolt face and gets caught underneath the bolt. I still don't get it why this only happens on the last round though, it should happen with every round.
