I've shot 125s and 147s in my M&P 9Pro with the stock spring with no issues.How well will this load work with a stock recoil spring?
Does anyone have a good recipe using 135's and WST?
I opened up my spreadsheet and I'm going to guess you are going to be somewhere around 3.7 to 3.9 grains of WST, but I have no idea what OAL with your bullet so work up from low. Real low!
I load:
J&K 125RN with 4.4 grains @ 1.145
and
J&K 147 TC with 3.5 @ 1.110
Edit: Both of these put me at about 135PF in my gun.
