The cartridges would not feed from the magazine or hold themselves in it for more than one so that required a little though and a remedy.
A piece from an old vehicle roof rack support made a dandy cartridge follower so I could save to original one unmolested.The follower needed to be narrower at the rear so I made it to exactly the width of the spring. With the turn up at the front and the turn down at the rear it was a perfect fit for the rimmed cartridge
I used some .040 stainless and made up an insert for the mag that would be held down by the spring and shaped the top to make it center feed and after a few trial re-shapes of the feed lips and the spacer folds down the back edge I finally got it to hold and feed

click on this short vid of it feeding. There was one hiccup but I found that I was occasionally running into the feed ramp so I opened the front of the lips a smidgeon to let the nose rise a fraction sooner and it fixed the problem. I didn't take another vid after the fix
