Anyone out there use Hogdon's Auto-Comp in a 9x18 Mak?

Nope. Cant find any data on it. Being between AA#5 and AA#7 in burn rate(not really an indicator), I'd say it was less than ideal in 9x18.
I've tried AA#5, did not like, uses a lot of powder, leaves unburned powder.

I use 3gr of Titegroup with a 95-98gr lead bullet.
Compare to 5.0-5.6gr of AA#5.

AutoComp seems tailored to 45cal.

If you try it, please post your results.
