picked up a 1000 124 fmj at P&D yesterday only to find that there is only two powder choices in the sticky, don't have them. I was thiking of using the data for the 125's with universal at 4.3 to 4.9gr? any opinions?
 
9mm loads

My Hodgdon #27 load manual lists 6.2 gr as max charge for a 125 gr fmj with unique c.o.l.1.150 , 1170 fps , 31 300 psi . and 6.0 gr max , 125 gr lead , 1.150 c.o.l. , 1165 fps , 29 400 psi . use accordingly depending whether your bullets are true fmj , or copper washed projectiles will determin whether you load for fmj or lead velocity and pressure !!!
 
From the Alliant website

9mm Luger 124 gr Speer GDHP Speer 1.12 4 CCI 500 Unique 5.8 1,180

So if you do the standard 10% ( SOMEONE CORRECT ME IF I'M WRONG) that would make the starting point at 5.2 and the Maximum of 5.8
 
I load 4.3 gr of unique behind a 124 gr Frontier CMJ, it also works very well with 124gr Cactus plains LRN as well.

My manual lists 4.0 to 5.0 gr of unique with a 124gr FMJ bullet.

I found under 4 gr. of unique to be a little "dirty" but 4.3gr is as clean as any other powder that I have tried.

I worked up a load starting at 3.75 to 5gr in .25 gr increments, and 4.25 was the best, so I tested a batch from 4.1 to 4.5 in .1 increments, and 4.3 is the best group in my pistol.

It works well in my M&P9, M-213 & in my buddies CZ-75. With my M&P I get 4" to 5" groups at 25yrds from a rest. And I get all the rounds on the paper with a 10" slow fire pistol target at 50yrds using a rest.

I developed the load for my M&P, its a real bonus that it works well in all my 9mms.

I have also tried titegroup, Bullseye & w-231.

I had simular results with the Titgroup (at 3.6 gr.) but I was unable to find any more TG so I had to find another powder.

I tried the bullseye but I had terrible results (not all of the rounds would hit paper @ 25yrds) and I had simular (good) results with the 231, It worked well in my M&P but not in my 213.

Needless to say Unique is my "new" favorite 9mm powder!!!

YMMV

Cheers!
