Zero 185 JHP -W231

Is anyone using W-231 powder behind their .45  Zero 185 JHP ?  If so what's your favorite recipe?

on my list this year to try 231 again with JHP.

5.0-5.5gr is a good range to look at.


most forgotten powder  we used to use years ago along with red dot

some information here: http://www.shootingtimes.com/editorial/loads-for-the-bullseye-shooter/99418

I loaded HP 38 (same as 231) for about a year.   I looked back at my notes and found that I loaded it to 4.5g.  The crimp was .469".  The face of the case to shoulder of bullet was .920".  I lost my velocity date when my computer died but I think it was around 770ft/sec.
This load cycled my gun very well.  I have a range officer with a kart barrel and slide mounted matchdot II.  The recoil spring is 9 lbs, and the main spring is 18 lbs.

For my lead 185 grain swc I have used 4.8 grains of HP-38, shoots well.  I think I could dial it back to 4.5 grains with no problem.  I know that is not the bullet your talking about but I would think you would do fine with it on the bullet your talking about.

5.5 grains works for me. 18 lb spring

4.2g works for me in a new Kart barrel. With the old Kart barrel that came with the pistol
I had to bump the load up to 4.8-5.0 to get it to cycle. Very accurate for me.

Thanks for all the responses.  It's appreciated.
