I have been reloading bullets for my 110E .270win for many years without any trouble. I use rem. cases, federal LR primers, nosler ball. tip 150 gr. and 50 gr. imr 4350, and size them to specs from the nosler book. The last time I used the gun I was having trouble with the fired cases being very hard to eject, and the primer was flat. My local gunsmith told me it looked like too much pressure and said to drop 2 grains of powder. I tried that, and it seemed to help, but when I ejected a live round, the tip pulled out of the case. I then tried a factory remington core lock pointed shell, and it pulled that tip out of the case, too. What could be the problem, and how can I fix this? This is one of my most accurate rifles, and my favorite to hunt with. Also, my remington 7600 .270 shoots these same reloads with no problems. Here is this years piebald 6-point I shot.
