Tell me what I did wrong. I reloaded about 50 cases of brass that I had fired in my rifle. 270 Winchester. I only neck sized the cases and then loaded them with 130 grain Hornady SST. About half the rounds feel like they are binding when I try to close the bolt and about 10% of them the bolt won't close at all. I don't recall whether I trim the cases or not as I loaded the ammo couple of years ago. I'm thinking the cases probably grew in length and aren't able to chamber. Tell me what I did wrong and how to correct it, please.
