I don't think this guy was quite that dumb, but maybe... in any case, I get the same issue now as in these photos of his, and I'm definitely loading 6.5x55 Swedish, according to ammo box and headstamp.
So at this point, what would you guys recommend I do? Start by buying a replacement mag spring, and then start looking to do some light sanding if that doesn't fix the issue? I think I might be able to source a mag spring or two from a friend who works at a gun shop over on the west coast.
