I am kicking around the idea of building a 338 Edge and was wondering if anyone has first hand info on this cartdrige. I have read that alot of them are built on Rem 700 action (300 Win Mag). I don't own any Rem actions and was wondering if the 338 Edge would fit in the magazine. I know you have to open up the feed rails so it can feed the round. Thanks in advance for any info.
