Have been having 2 problems with my custom 28 Nosler. First is reloading once fired brass (using Nosler brass). Loaded up 195 bergers with 85.5grs of RL33 and 215m primers. New brass loaded without a problem. During second reload having problems chambering the rounds. Tried full resizing same brass and still not chambering. Measured the case base and same width for those which chamber and those which do not chamber. Tried chamfering a good edge which doesn't help. Checked overall case length and well under what I measured the chamber. Neck turned some which actually helped for only some of the rounds. Measured all the bullets and are all within caliber specks. I'm out of ideas and was hoping someone could help. Problem #2 is that when the smith chambered my barrel he extended the throat about .150 more than I asked so that is what my current jump is. Can't load the bullet out farther due to magazine length restrictions. For this problem I'm thinking about just finding a smith with experience building the 28 Nosler and re-barreling again. Just for completeness purposes the rest of the rifle is a Stiller predator action, Bartlein barrel, pillar bedded in a McMillan HTC stock.
