I finally found something I could use CFE-P for and that's it! 180 - 187 bullets from my 3" revolvers give 900-925 fps. Recoil and blast are not offensive. Great accuracy. IIRC I settled on 5.6 grs. Very low ES & SD. But I can double check that charge if you like.
I'm not sure it would go super sonic from a rifle but the load could be cut back a little. Worth a try. HP38 might be a good choice, too as it's a little faster burn.
