More work on the AR 22 Mamba Magazine
Working on the AR 22 Mamba 10 Round PMag
Feeding more than 3 rounds has been problematic, the cartridges cant with 4 or more in the magazine and end up more or less vertical at the throat. Jam-o-matic.
George and I discussed possible solutions, and short of modifying the magazine follower, or extending the lips, reducing spring tension may help. (Mockup in Photoshop of an extended lips magazine.)
I got radical, and after fixing the follower I had previously butchered in search of part of the solution, I cut 3 or 4 coils out of the magazine spring. (See pic.)
You will need bolt cutters, heavy duty wired cutters, or some kind of cut-off wheel. I used a Dremel abrasive cut-off wheel and then bent the spring at the the place I had been trying to cut with pliers and side cutters, and snapped the spring.
I think that cases loaded to about 1.6" or longer are the best candidates for a standrd magazine, with the bullet tips as close as possible to the front of the mag.
Before the cut, 5 rounds would not feed without a jam, after the cut, 5 rounds fed and ejected correctly in my reloading room. The range is the real test.
