I'm working up loads for a FN Mauser chambered .30'06. Most of my loads so far, and the factory loads I originally tested it with, chamber fine. But, I just loaded 15 rounds and 11 of them are difficult, to near TOO difficult to close the bolt fully.
COL is fine, same or shorter than any other loads I've run through it and over .2 shorter than max. Same sizing die I used for all the other loads, as well.
Considered maybe I didn't deburr the brass cleanly enough, but it doesn't seem to be that. The case necks are smooth.
The only time I've encountered this in the past was when I had a COL issue; a load for one rifle loaded almost to max length, tried out in another, and the chambers differed just enough to be an issue. I figure somebody here has encountered a similar problem, might have an idea of something else to check.
Thanks Much-
Andy
