Herco would be a great powder for 9mm if you are forced to seat the bullet deep because of chambering issues. It's a slower powder that won't go overpressure very easily and spills over a 9mm case if double charged. At the beginning of the powder shortage, I had a chance to buy an 8# jug of Herco, but since I had just bought a jug of Unique, I thought I was set for a while.<wrong>

I also really like 800X's performance in 9mm. It behaves very close to Herco but the flakes are HUGE


I finally found a pound of BE-86 and it is also right there with Herco and 800-X, except it meters beautifully. If I can find an 8# jug of it locally I'd scoop it up in a heartbeat. In the mean time, if you have Herco, use it. It's great in low pressure cartridges like 38 Special and 45ACP, but also works well in small case cartridges like 380 and 9mm.
