Whats up guys, anybody running AW magazines with cartridges that have the 308 as a parent case? For example, I have a new rifle i built in 6XC in a stiller Tac 30 A/W action and I want to make sure that the 6XC's will feed before I splurge on these mags. I'd hate to try and make it work then not be able to return if it won't feed properly since I will have "used" it.
