Gunsmithing remmy 700 mag

[Bevan]

I've got a 700 SA off being rebarreled in .223AI, I want to run the 75gr Amax... and I want to increase the factory mag length a bit so I can seat the 75's out a bit. Any suggestions?

Cutting the block out of the back of the mag would be the obvious route to go

Take the block out. Cut block in half. Re-weld it back in.

Thanks.... so the follower doesn't cause problems when it has a bit of play back + foward?
