I'm pretty sure there has already been a thread in reference to this but I was unable to find it. I picked up some W231 to try with my 9mm loads. Have you all been happy with the performance you've been getting?   What load have you found most accurate?  

Just for reference its for a full size M&P using 9mm Rainier 115gr bullets, random brass, and Win SP primers.

Disclaimer: yes I know I need to do my own work up, I was just curious what everyone else was finding to be accurate and your experiences.

Thanks for your help and comments!!

I have used W231 for 9mm a lot! I'd have to dig out my load data to get the exacts but I love it with lead round nose out of my G17. When I was working up my first loads with it I did get some key holing until I got them loaded heavy enough. Too light of a charge with W231, lead round nosed bullets and the G17 will key hole. Also, too much charge with this same set up will get some leading in the barrel and that will cause issues also in a Glock. It's all part of working up loads, keep your notes and you will eventually come up with something that will work for you.

Oh the W231 is smokey!!! But I love it!!!!

4.9 will give you 1085 fps in a glock 19c

I've been using 5.0 grains under any 115 bullet  in a Taurus PT-99 and both my Kahr 9's for years with zero issues.

I found 4.6gr to work well for me. Here is my thread from a few months ago when I was loading my first 9mm: WIN 231 Troubleshooting

4.6gr w231 with 115gr rn at 1.135 oal was my first load that shot amazingly well in 4 glocks and an m&p.

However I greatly prefer 147gr over 3.7gr w231 also at 1.135. Softer shooting, more accurate and I daily carry 147gr so it's nice for muscle memory to practice with.

hello;

great powder.  hp38=w231.  for some reason in my area hp38 is $2 per pound cheaper.  load 3.5 grains, 124grain lee t/l bullet, speed is 915fps-ish.  light load, cycles in all 9s i have.  this load shoots to the same p.o.a. as my defense loads, win. 115 grain h/p (bass pro brand).

BIG advantage to me, ww231/hp38 are ball powders, set your powder drop to 3.5 grains and it drops the same 99.999% of the time.  may load 500 at one time and the last thing i want to do is confirm the weight of each drop of powder.

Yep, I've been using 4.9 grs. of W231 in my 9mm, 115gr loads for years and years.  It gives excellent accuracy and performance in my two 9mm pistols.  W231 is also my goto powder for .380 acp reloads.

4.6gr behind 115gr plated Rainier, with a OAL of 1.150".  I load for my dad's full size and compact M&P, and for our 5906's

3.8gr behind 147gr plated Xtreme, with an OAL of 1.155".



When it comes to practice loads, W231 is my default powder for 380acp, 9mm and 45acp.  It's just so handy across those three calibers.

Works great for me as well.

3.8gr 231 over a 124gr LRN, 1.100 OAL (short for my CZs) –– very light load that cycles all of my guns just fine, no leading, accurate, inexpensive. Fun.

For certain combinations of bullet weights, I don't even have to change the charge from 9mm to .45 when using W231.

With a Baretta M-9 Service Pistol, I was getting short recoil/failure to eject until I increased the charge to 5.0 gr W231 and 115 gr FMJ bullets (Federal SP primers).

Mine work better with the bullet over the powder.

I use 3.9gr with my 122 gr TC
