Where can I purchase a mag for rem. 700 that will feed the 6mm br.Or does someone do custom work to make my rem. mag. work. I've seen a post where someone shows the pictures of how to block the mag. and cut the follower but I have no tools or even a vice to hold the mag. so I need to purchase one or pay for the work to be done. Either way works for me, any help would be nice. Thanks in advance
