Hey guys, just wanted to share some load data I got for standard pressure 45 colt in a 20" rifle barrel using WST. I havent seen many threads or info for this powder so I figure I'd make my own. Its a great clean burning powded that has a very similar charge weight to titegroup in my experience...but it burns much cooler, and a little slower. Ive used it in 45 acp, 9x19mm, 45 colt, 45 colt+p, and 44 magnum so far. In this test I also used different kind of primers for each 10 shot group.
1. Bullet: Nosler 250gr JHP
Brass: Winchester
Primer: Federal Match
Powder: WST
Charge: 6.2gr
OAL: 1.600"
FPS: 886
SD: 17.3
Comments: recoil was lighter, brass had low pressure signs and powder residue due to not having enough pressure to seal to the chamber. Primer okay. There were no unburnt grains left in the case, this is what I consider to be a "clean" factor. I hate unburnt grains left in the chambers on my guns, especially revolvers. But there were none in this rifle chamber.
2. Bullet: Nosler 250gr JHP
Brass: Winchester
Primer: Federal Standard
Powder: WST
Charge: 6.2gr
OAL: 1.600"
FPS: 883
SD: 14.0
Comments: same as above.
3. Bullet: Nosler 250gr JHP
Brass: Winchester
Primer: CCI standard
Powder: WST
Charge: 6.2gr
OAL: 1.600"
FPS: 897
SD: 10.2
Comments: same as above
4. Bullet: Nosler 250gr JHP
Brass: Winchester
Primer: Federal Magnum
Powder: WST
Charge: 6.2gr
OAL: 1.600"
FPS: 898
SD: 15.1
Comments: same as above.
After that test I decided to bump it up to see if I could get a proper seal to the chamber to clean it up a bit.
5. Bullet: Nosler 250gr JHP
Brass: Winchester
Primer: Federal standard
Powder: WST
Charge: 7.0gr
OAL: 1.600"
FPS: 991
SD: 15.2
Comments: 70% of the brass sealed to the chamber properly and was 100% clean. Recoil was still light, but noticeably heavier. Primers looked to be slightly flattening, but not very much. I'm kicking it up another .2-.4 grains next time.
Attached is a picture of the brass in order starting at number 1. You should be able to see the reside and the primers.
Thanks!
