I'm running 3.3gr of bullseye behind a 124 j&k... and it's a powder puff load i think... cycles fine though. loaded to 1.125

Hi,

Just so you know, the 9MM cartridge isn't a straight walled case, there is a slight but obvious taper. Here's the measurements.

ldp4570 is absolutely right, it has a slight taper which can be troublesome in resizing depending on your resizing die. This is why some 9mm rounds come out looking like a coke bottle - many manufactures take the cheap route and put a small height carbide ring in their sizing die which essentially will "straight wall" a 9mm case up to a certain point. Redding Pro Series dies do the BEST job of sizing 9mm with a full height carbide ring. Lee also do a very good job and their dies are quite a bargain in 9mm.

9mm is easy to load. There is no roll crimp, just a taper crimp, but that really is simply unbelling the case. The true bullet case tension comes from the sizing process. 9mm brass is also incredibly strong, if loaded with reasonable 9mm load data you should have no issues. As with all brass, I'd inspect each one though.

Good luck,

Alan

I was running about 4 to 4.1 grains of Win231 with J&K's 124s with plenty of success. My Pro cycled well with them, and my lawn mower had more kick than that load.

That said, I've bumped my load up to about 4.3 to 4.4 grains. The lighter load was pulling about 125k to 127k power factor, but it was so soft that steel poppers took FOR-EVER to fall down. The bump in power is so slight I can't feel it in the gun, but now it knocks stuff down with some respectable speed.
