I hope its better then Power Pistol in 9mm. I have to come to terms w/ and overall length today for my C-Z, M&P9c, Lone wolf conversion for 40glock in 9. It the 124g FP EXTRM. don't have a prob. w/ the other 2 bullet profiles. P.P. is scareing the neibors off! But I no its good for 9mil.
I've had great luck with Power Pistol in 380, 9mm, and 40. I load only reduced recoil, not going for max velocity. Burns clean, and is consistent. Some people complain of the muzzle flash, but it has never bothered me.
Back to the OP. I have loaded Extreme plated 9mm 115 RN with Titegroup, have tested it through the range from 3.7 to 4.5gn. I personally like a load of 3.9gn, seated to 1.135 COL. I got 1033 fps, 12.3 standard deviation, 40 fps spread with that load, out of a 4.5" barrel.
But, as always, start at the lowest load listed on the powder manufacturer's website and work up from there, as YMMV.
I've read in several places that Titegroup is supposed to be "peaky" or whatever, but it has worked well for me in 9mm, 40, 38spl, and 45acp. It is one of the powders that if I see it, I will buy more of it.
