OK, I have a bunch of al. checks that I am using on my 308win rifle. I am also reloading for 2 Mosin Nagant rifles. They both need to be sized at 0.314" Now here is where I think I might run into a problem with the al. checks. When they are sized to 0.314", the check is at 0.311" and the rest of the boolit is 0.314".
Now do you think this is going to cause any problems, or will the check bump up upon firing?
I am thinking I need some thicker checks to take up the difference. The shank on the boolits are the same as on 308 win. boolits. 0.284" So the 0.014" al. checks don't have enough thickness for the larger boolit. Am I right on this?
