WST for 40 Major?

[shtr3]

Guys, I have done searches and read for an hour or two on this subject and found some very outdated material. So I am going to go ahead and post this question. Do any of you use WST for 40 major PF. Im looking for some load data on this. I have 180 gr. Bayou Bullet that i will be loading, which is lead moly coated. I use 4.2 gr of WST w/ 230 lead round nose in my 45 and get around 175 PF. Just picked up a new limited STI pistol 40 cal, which i will shoot in Limited Division and was wanting to get educated on this, if anyone uses it, using it, or has used it to get major PF.

Thanks in advance.

I think my buddy uses 4.1 or 4.2 with a 200 grain bullet in 40. His PF is 170-171

170 gr, Lead

4.0 870 22,800

5.0 970 30,000

I just used 4.0 gr with some 180 gr xtreme bullets today. Around 85F here and out of my P229 I averaged 756FPS. 1.160" CCI Small Rifle Primers I think, they might have been pistol but I can't be for sure only because I primed the brass so long ago and have been shooting 45 for so long.

4.6gr at 1.185 with a 185gr Precision black bullet gets me 173pf & 4.2gr with a 200gr Bayou Bullet at 1.190 just netted me 176pf at the Area 7 chrono. These are out of an STI Edge.

Same drops and oal for me got about the same results...... You will be fine with these....

WST is reverse temp sensitive

4.3 to 5.5 grains of WST with 180 grain bullets depending on your barrel, bullets, cartridge overall length and the temperature of the ammunition. Sorry, that I can't be more helpful, just work up slowly.

Perfect info I needed, same gun, almost same bullets. thanks, this will help me a lot

180 gr. Bear Creek FP

Hogdgon's website shows a maximum load at about 160pf at an O.A.L. of 1.125" with WST and a Hornaday XTP 180gr bullet. I don't know what temperature their test ammo was fired at; I'd guess probably room temperature. You might have to push it to get major in hot weather, but I guess it also depends on your barrel, bullets and a bunch of other things. Cha-Lee once listed a bunch of things that effect pressure. I'll look for his post. I may have saved it somewhere in my hard drive.

My mantra is "Work up loads slowly."

4.7gr of WST @ 1.140 with a BBI or Bayou 180gr bullet gives me about 168 PF at 95 degrees.out of my STI 5 inch Eagle and Sentry. Start a little lower and work your way up with a chrono.

[co-exprs]

I've been running 4.3gr WST under 180gr Bayou, 1.180" OAL in my .40 STI with a Barsto barrel. Average velocity= 945 for a PF of 170, in 90deg heat. Shoots soft and clean. Only complaint is the velocity is a bit more eratic than I would like with about a 60fps spread. 4.2gr Solo1000 gives me the same velocity from the same bullet, is just as clean, difference in feel is nearly imperceptible and the velocity spread is about 20fps.

Here's a link to my load data with WST and Precision Delta 180gr FMJ out of my Glock 24

When loading the 40 S&W to major at the shorter SAAMI lengths for a Glock, S&W, etc. I always recommend avoiding the faster burning powders like WST, TG, etc.

It’s just not worth the risk.

good info, exactly what i was looking for

[BASE772]

4.9 WST under a Precision 185 @ 1.200 is my favorite major load.

[Lifeislarge]

Just spent the last hour working up a load with WST. Started at 4.8gr with a 180gr JHP loaded to 1.202. Finished at 5.2gr and will post chrony results when I get them. Shooting my STI Edge. Temp will be around 80 degrees.

[feederic]

Opps, forgot this.

5.1 grains @ 1.21" . Berrys plated 180gr RS.

These RS didn't like to feed at "standard" long lengths. I was able to make major with 4.6 at 1.18 though.

Do that, and let me know when you want to shoot.

5.0 or 5.2g of WST at 1.170 to 1.180 should get you Major, in my SVI barrel i'm getting right over 900fps. In my Briley getting a lot higher because of a faster twist, around 1000fps.

[Lifeislarge]

5.2gr averaged 939 fps through 10 rounds with a high of 954 and a low of 936 making an average 170pf. Better yet, it shoots way softer than the Unique recipe I was shooting. I've got 4lbs to load so I'm thinking that I might have found my new powder of choice until things settle down some more. Now all I need to do is find more bullets.
