Anyone have a good "SAFE" stiff load for the new vaquero. A lot of companies say on their ammo "Not for new ruger vaqueros" Because they are not made as heavy as the old style. Im trying to reach 400 LBS of energy at 50 yards. Anyone have any more info for my revolver?

OK....
the SAAMI limit for the 45 colt is 14000 psi, a limit safe for the older Colts.
If you stick to this standard you get this.
