Power Pistol in 38spl 125gr cast??

[LubeckTech]

Is Power Pistol unsuitable for cast 125gr bullets in 38spl??
The reason I asked is I can't seem to find any load data for this.
I have a Ruger GP100 Wiley Clapp (3" barrel) that shoots a little high with 158gr cast bullets going 800-900fps and I am looking to establish a load to bring it closer to it's sights. I want to get a light cast coated bullet moving about 1000-1100fps in hopes of accomplishing this. Got a couple of loads ready to chrono but want to try some power pistol. Might try 6.0gr to start with.

My Hodgdon manual lists 6.3 grains of Power Pistol as a +P load with a 125 jacketed, at 17,200 Psi. Plenty safe in your GP-100. I'd expect a little less pressure, and a little more speed from your cast. Velocity is listed as 1,165 fps. from a 7.7" test barrel.

The Alliant manual lists 6.3 as +P for .38 spec. with a 125 gold dot hp and 10.5 in the .357 mag with the same bullet.

That's what I had been seeing for jacketed too and my reason for starting at 6.0gr. I can't see any reason why there would be a problem with it in a cast load but found it odd there don't seem to be any listed loads.

My accuracy load in .38 Spl is a 150 gr. RF with 5.5 grains of Power Pistol. You will be plenty safe with 6.0 and a 125 cast.

What 150 are you shooting?

I just bought some power pistol. I was looking for in the Unique range.

power pistol is a step behind unique and a step ahead of Herco.
this means you can use unique data to get started.
it's right there with BE-86 as far as how it burns and acts in pistol cases.

I finally got to test my initial load of 6.1gr of Power Pistol and found it to run right around 950fps with both the Lee 356-125-2R and 356-124-TC sized to .358 and tumble coated with Harbor Freight powder coat paint. They weigh 127 and 130gr and are accurate.

6.7 gr Power Pistol behind a Lee 125 rnfp gave 1020 ish avg from a Ruger SP101 3". Damfine load.
