Big Wonderful Wyoming7mm Blaser
I ended up with 425 rounds of new Norma brass.
Found a guy that had a reamer and has a good reputation for building long range rifles (Shawn Carlock).
Going to be a fun gun.
7mm Rem Mag plus-P power without the belt.
Hopefully it will feed out of a AICS magazine.

The .300 Win Mag AICS magazine has a vertical, raised internal rib positioned just in front of the shoulder of the cartridges. I tried using one with 300 H&H and it gave me trouble because the shoulder of the H&H goes beyond that point. The ribs on either side of the magazine were binding against the shoulders of my cartridges and causing all sorts of feeding problems. If I had a milling machine and the know-how to use it I would have removed some or all of the ribs. The fix I found was to use Magpul plastic magazines. I removed the bottom of the magazines, took out the spring and follower, then sanded down the ribs to about 1/2 of their height. It was easy because they are plastic. I reassembled the magazines and they work just fine.
I think your situation with the 7mm Blaser will be the opposite, i.e. the rib will be in front of the shoulder (~1/4" ?). Whether that creates a problem or not remains to be seen. However, I suggest you purchase an inexpensive plastic PMAG to find out, especially if you need to work out some sort of modification.
