I had the first problem out of it this past weekend at a informal shoot with some friends. Case swelled and stuck in the chamber. I tapped it out very easily with a cleaning rod, but kept the brass and compared it to other spent brass and it definitley swelled. Assuming this is cause by out of spec brass or over charge?? There were no noticeable burrs on the case and my chamber looked good with no gouges or anything.
But now I am definitley going to check the 1200 rounds or so I have left of the Olympic, what do I look for and how do I check to make sure the brass is within spec, hoping I do not have to remove the bullet and check it that way. I do not reload so I don't have dies but I dial calipers and micrometers for my car hobby can I use them to check them out and make sure they are ok? I know I cannot check the powder load without pulling the bullets.
I also thought maybe it was because the rifle was hot and caused it to swell? I shot probably 300 rounds pretty much non stop and it was pretty damn hot, but I am sure our soldiers fire that much and more at one time during a drawn out firefight so I dispelled that on my own, but is it a possibility?
