5.5 grains of Unique, once-fired Sellier & Bellot case, Winchester small pistol primer. Alliant lists 5.8 as the max for a 124-gr. slug but I stopped at 5.5 because velocity was a little faster than it should have been and I was concerned about pressure getting out of hand. Velocity was about 1,190 fps. Extreme spread was around 25-30 fps. Standard deviation was in single digits.
I cut the charge to 4.4 for the cast .358" cowboy bullet.

Thanks, okie john. I've killed lots of deer with a pistol, mostly in .45 ACP/AR, but finally popped one with the 9mm last year. One shot and crash in its tracks...

You're welcome. That outcome isn't really surprising.
The deer around here are tiny and shots are usually inside of 30 yards, and I've killed several with .429" and .452" bullets at 1,100 fps. I've wanted to get one with a 9 for a while now, and a fast 124 seemed like the best balance of trajectory and bullet weight. I zeroed that load an inch high at 25 yards, which put it an inch low at 50, so even if the typical range doubled I'd still be OK. But it looks like the game regs have changed on me this year, so based on GJM's posts about the HK USP 45, I'm testing one of those.
Vamos a ver.
