To be clear, I meant only nickel-plated ammo. Nevertheless, they must've changed their primer cups for the nickel-plated cases. I haven't bought nickel-plated factory ammo nor new Win primers in over 18 months.
I should have been more clear myself. I am talking about nickel plated cases in ballistic silvertip loadings in .223 , 270 wsm and 300 wsm.

yes, it sticks when closing at that point, It is hitting what I guess is the receiver but if I push down on the handle it will go in without more than a click there. Or if I push forward with force it will hit then rotate slightly and go in.That is, when you're trying to chamber a round?
yes, when chambering or closing on an empty chamber.Or this is where it sticks when you're opening it? The bolt looks unlocked to me in that photo, and it looks like the bolt face is just about at the receiver opening. What am I not understanding?

Something's a bit different between the chambers on your rifles. Probably just a little larger chamber/body size in your 270's chamber vs. the 300, or possibly a little greater headspace. That would let the 270 brass expand a bit more upon firing, and prevent it chambering in the 300 thereafter. It could be other things, I suppose, but I'm thinking that's about the most likely thing.
As far as the crimp marks you're seeing. I cannot immediately explain to you why they look different after firing vs. before. Nevertheless, it is what it is. Those marks are relics of the factory loading operations. If that was rifling, then the crimped-in portions would be relatively narrow, and the un-crimped-in portions would be relatively wide. This is because the lands are narrower than the grooves in the rifling. Then there's that thing about how you wouldn't be able to chamber the rounds at all because you'd be pushing the entire exposed bullet bearing length through that rifling.
I still hold the opinion that it is not completely clear whether it's the gun or the ammo that's causing the problem here, but I've been wrong before and no doubt will be again many times. :)
