I purchased 150 pieces of Winchester brass for my 220 Swift, as my old brass was starting to split case necks and I had more than gotten my money's worth from them. So, I loaded up 25 rounds without FL sizing them and went to the range. ( I know, I should have.) At the range, 6 of the 25 would not chamber in my Savage Model 12.
When I got home, I checked the shoulder dimension with my Hornady comparator and sure enough, the shoulders were about 6-10 thousandths longer than my fired brass. So, I figured I would bump them back. Boy, did I get a surprise. First, my Lee die would not push the shoulder back to the desired length, so I got out my RCBS die. After lubing up the case, it would not fully reach the case holder no matter how hard I pushed. The case also got quite stuck.
After getting the case out and ruining the rim, I got out my 0-1" mike and measured the head diameter of the case. It was several thousandths larger in diameter than all of my successfully fired cases. No wonder they weren't full length sized. Next, I got out all the new brass and started checking it all. All the long ones had over sized heads. I'll bet 1/3 of them are rejects.
Now, I know I bought cheap brass but this is ridiculous. It's the last Winchester brass I'll buy. Anyone else have this problem?
