So I'm working on batch loading some 357 mag rounds, and came across some very tight primer pockets. I noticed a couple shells took a lot more pressure to seat the primer. One even had a small amount of shaved metal from the primer. The primer pocket on a few of these have no chamfer around the edge, they are straight walled. This is the best pic I could get of it, the one on the bottom right is normal the two on left are the tight ones. No problems that I remember depriming them. Any ideas, there isnt' many, should I just toss them?
