Does anyone make a powder funnel that works with short mag. cases? I know about alterations to existing funnels, drop tube attachnents, etc. You would think someone would have a good funnel on the market by now!

The "Smarter Powder Funnel" that Midway sells will work. It's been some of the best $13 I've ever spent on reloading equipment. It's marketed under the Frankfort Arsenal brand now, but it's the same thing. Has a different nozzle for each caliber. It would work just fine for your short mag.

The newest one I bought from RCBS would probably work.....problem is that it sucks for standard cartridges. I bought it from my Ackley.
