Actually, I have had a LOT of experience with the 25 ACP, both in terms of reloading, and choosing a good gun.

After going through a bunch of guns that always seemed to jam, the one that was hands down reliable is the Beretta Model 21-A. Beretta calls it the "Bobcat" model. It loads with the first round manually placed in the flip up barrel. I have thrown a bunch of different rounds through it, including many factory cartridges and my own reloads, including a cast lead bullet load. Not a single failure to function.

I bought an out of production Lyman mold that casts wonderful 50 grain Round Nose bullets. I also managed to acquire an out of production conversion kit for the Dillon 550b. Those are very rare and hard to find. I use Titegroup powder for the loads, and it seems to work great.

That's my two cents worth.
