Got the barrel, lug, new nut, bolt head and tools on the way. I have one question I am trying to work thru.

The magazine is connected to the action and is stagger feed. I looked up my serial number on the savage website and the mag is part number 100191 and follower is 102981. I am trying to figure if I need to replace the Mag and follower. On Midway site it states the savage part number 100191 is for 30-06 and 270.

Is this the same mag? Will I need to replace it? I have some ammo and brass ordered, but not here yet. I will be shocked if the 6.5x55 round will work in the 7mm RM mag.

The reloading references I have state that the diameter of the 7mmRM is 0.532 and 6.5x55 is 0.480.

Can someone advise me in this area? I have looked into how to take the mag off the action, but no luck so far.
