Well GS agrees, the chamber is long, just over his match gauge, and the receiver where the breech block locks up is worn which allows some setback when the rifle is fired. The FL Lee die is pushing the shoulder back to minimum SAAMI spec. In his opinion partial sizing brass will extend case life without any safety issues. He also recommends I keep my loads in the lower range. I do this anyways. We discussed taking the barrel down a thread but decided to try the partial resizing first. I have a collet die for .308 and I will also try it to see if the rounds close with only neck sizing.Ohio3Wheels wrote:I had a similar problem years ago with my 6.5-06. FL sized cases (die contact with the shell holder). I didn't have a good way to measure back then so I started backing the die of a half turn at a time until the cases chamber with some effort with a quarter turn back in they chambers and the bolt closed with just a little effort. I disposed of all the cases I had on hand, got 20 new 30-06 sized and loaded and ran them through the gun. After 5 firings I couldn't detect any ridge inside and no bright ring. Not a lot of need for the long range capability here in SW Ohio since civilization has crept into the areas where I used to varmint hunt out to about 400 yards so I don't shoot it as much as I used to.
