Not sure how to change this as the mag sits against the ejector and the round sits right below it. I can recontour the bullet guide but that stubby nose is the problem. Possibly a ballistic tiped round would work as is, but I want to use the "flying ashtrays"
After about 6 hours on the mag I just gave up and tried a M1 Carbine mag, and the damn thing worked first time and every time. The 15 rd holds 6 win mag, Guess I just gotta resize the mag well, give up on a BHO and figure out a mag release/triggerguard
What kind of magazine are you "making"? I'm guess you're either adapting a mag or bending sheet metal? I'll be honest, I was thinking about making my own box mags for this. Perhaps a 20 rounder?
I think I may be able to help with that. After spending a few nights just looking at the magazines and scratching my head, I think I know how to make the 45 straight cases feed properly.
You and I have the same problem. The .45 in an AK magazine feed system. The .45-70 is of course different than 45WM, but the feed ramp area is basically the same. If you look at the way a .410 or even a 12ga magazine feeds, you'll notice the front of the magazine is open so the feed lip sits "inside" the magazine. At least, it sits below the top of the magazine.
The same application is made to the Uzi magazines. The front of the magazine is situated in such a way that the round is mostly exposed.
The followers tilt the front of the bullets up just enough that they have less effort to move on the ramp, but not enough that the back end is below the bolt.
OK. To apply this to your (and soon my) build, I believe that if you trim your magazine at the front, and alter the follower so that it is pushing the front of the bullets up ever-so-slightly, you should be able to get them to fit. You may have to alter the location of the locking lugs, but now that I've welded AK lugs onto a dozen G3 magazines, I'm no longer "scared" of magazine alterations
You may have to tilt the magazine a few degrees - not much - if you find that the Angle of Attack (AoA, or Alpha) to the feed ramp is too steep. The AoA should be less than on a pistol, or even on an Uzi style design. I would guess that the extra space in the AK receiver would let you lengthen the feed ramp a bit.
That change would let you keep the BHO feature, assuming it is a standard BHO style that has an engagement lug at the back of the magazine.
