Ok guys, I have a 700 22-250 that has started to have some issues ejecting cases. It will pull them out of the barrel, but when the bolt gets back to where they should eject, a lot of the cases will just drop straight down to the magazine. This is old brass, probably eight reloads. I just bought new brass and some of them do it also. Is there something I need to do to help this problem, has cost me a couple doubles on coyotes.
