260 Remington Headspacing Problem
First of all, I am new to reloading. I have done a lot of reading and purchased more tools than I probably need. Anyway, here is my problem...I bought some new Lapua brass and it measures 1.264-1.625 to the datum.
I loaded some bullets and the once fired, fire-formed brass measures 1.629-1.630. I took an average of 12 shells for both the new and once fired brass. Now, I am trying to full length size the fired brass and know matter where I set the die, I can't come close to 1.629-1.630. The best I have been able to do is 1.6255. Most of what I have been reading says to bump the shoulder, in a bolt action .001-.002 but I can't come close to getting that much length.
This is a Remington factory chamber. And I'm using a Forster full length sizing die. Am I doing something wrong? Is my chamber too long? Any suggestions are welcomed. Maybe I can send the die back to Forster and have it custom honed. The gun is shooting well, so I don't really want to buy a new barrel right off.
