Powders for 9my 147gr coated

I am working up a load for hi tek coated Lyman#356637. My original plan was to use the pile of win231 I have accumulated, but looking for load data hasn't turned up much. Just looking for some input as to what everyone else is using. So far I have tried power pistol, titegroup and unique all of which I have published data for. I haven't found anything impressive yet.

I went ahead and tried win231. I started at 3.1 grains at 1.058 oal for an average of 825fps. Since my bullet drops from the mold at 156 grains I am getting just over minimum power factor. I may bump it up just a touch more for insurance, but so far I'm happy.

Who are you trying to impress?  9mm, 147gr coated bullets work well with just about any powder.  I've used as slow as Longshot, and as fast as Promo.  Use a suitable amount, and any in this range should be able to get you from the very high 120s to mid 130s PF.  My favorites are Universal and Promo.

Wasn't aware I was trying to impress anyone. Just looking for some information. Since I have been "coached" in the past I guess I will just say thank you for your input.

I was kidding.  You said you hadn't found anything "impressive" yet.

The twist rate in your barrel may have something to do with the tumbling, there are 1/10, 1/16 and 1/20 twist rates in various 9mms and accessory barrels.  I think a 1 in 10 twist rate would probably work better than the slower twist rates.

I couldn't leave it alone. Loaded up a few more with 4.2 grains of Power Pistol. Got the velocity up to 950fps and low and behold the tumbling went away and accuracy was OK, but not spectacular. I guess I'll be able to use up the bullets, but it isn't going to be the soft shooter I was hoping for.

I was using 3.2grains of Titegroup, then moved to 3.3 grains of N320 which was nicer (softer, not as hot, clean) but recently tried 3.8 grains of WSF for my 147 grain 9mm loads and was blown away.  Very soft and very accurate, also reasonably priced.  It's definitely worth trying WSF with 147gr 9mm
