In addition to the B & P Comp One loads which are in the 8000 psi range, there are these ........... Winchester AA Low Recoil Low Noise loads which are very close to 15/16 oz. (26 gr.) and are in the 6000 psi range. I would not hesitate one moment to use either of these loads in a sound 2 1/2" chambered gun with good barrel wall thicknesses. It has been shown that doing so only increases the chamber pressures a few hundred pounds at most, not enough to be concerned about. There used to be an "equivalent" load offering from Federal but, I don't know if they are listed anymore.
