Has anyone had trouble getting Alpha WSM mags to work in a Surgeon 591 WSM action. I just got one today and it won't seat all the way into the bottom metal. It seams like it is hitting the bottom of the feed ramp. Any help would be appreciated.
Do that and you can tell what needs to happen. If the magazine is hitting the bottom of the receiver before it latches then the DBM latch needs to be shorter or the DBM needs to be further out of the stock.
Compare the location of the locking notch on your AI magazine to the Alpha locking notch.
I had this same problem with one of my 591's in an AICS FWIW, but only with some alphas. I managed to get them all to seat with a LOT of pressure. It didn't negatively affect the gun or magazine in any way that I could see.
I had the same problem on a Type 2 mag and a 591 (standard face) I bought about new 2 months ago (C prefix action). I mocked up the Surgeon DBM to the 591 with the supplied pillars. Mag would almost seat; latch would almost catch. The 2 tabs at the front of the mag that hold the follower down were contacting the action just under the feed ramp as noted above. I just took a small hammer and tapped them down just a touch. I probably should have used a metal pipe about the same diameter as the action and hit that instead of the tabs themselves. I just tapped a lil and kept trying until the latch clicked in place. The mag fits snug in the dbm with no rattle at all. I run a couple of mags of empty rounds through the action alone (no barrel on it yet). Everything worked fine.
