Winchester 9x23 brass. Kidding. Kind of. Did the 9mm major thing. Like hot 38 Super, but especially my 9x23 Winchester best.

What Fred said.

What kind of gun are you going to use?

I tried using an old G17L, and all was fine except anything loaded over about 1.139" and you absolutely HAD to fire that round once it was chambered. A longer loaded round wouldn't eject; the bullet would hang up and no fiddling could get the loaded round out without dropping the slide and just shooting it down range.

Pay attention to listed COAL when you're using data for 9mm major.

No, it's more like eating beans AND broccoli at the same meal.

I found if I went longer than about 1.135" - 1.139" in my G17, loaded rounds wouldn't eject from the chamber but would hang up and tie up the gun. I had to count the rounds for each stage and only load exactly what I needed to run the stage... or fire the extra round downrange to empty the gun.

Found out the hard way on that. YMMV

Something is wrong with your gun.

I've loaded as long as 1.155" for my G17, and loading Bear Creek Molys to 1.145" for it now. WWB are right at 1.160" and I shot 4-5000 of those before starting to reload. How many people are there who don't reload and have no problems with that? I never had an issue.

Nothing was wrong with my gun. I don't know if the newer 9mm Glocks have a larger ejection port area or not. This was in about 1988 or so. But I'm telling you, anything loaded longer than 1.135-1.139 was too long for my chamber. I was loading 147 grain Speer fmj.

As soon as I started loading to 1.135" everything ran 100%
