Starting point for making minor in a PCC with Sport Pistol


Recommended Posts

I have some 115 and 147 grain plated bullets and some Alliant Sport Pistol that will be run through a 16 inch barreled PCC and would like some info on charge weights that give a power factor of at least 125 and no more than 135PF.

 

Pistol loads would be great also as a 125-130PF in a pistol will obviously be higher in the rifle.  I'm looking for some help to try and save on components as it looks like the components I have on hand will NOT be replaced for a very long time............

115gr plated 

1.125" OAL

3.9gr ASP

Fed SPP

Mixed Brass

 

12" Barrel

4" Brekke CompXtension

 

135.9 PF at Mid-Atlantic

135.8 PF at Area 8

 

3.8gr ASP was around 130 PF, but my SD/ES were cut in half (20 to 10 SD) at 3.9gr.

 

The outside of the fired cases are still very sooty at 3.9gr. I don't think theres enough powder for the most efficient/clean burn at these levels.

Meanwhile my pistol loads (135gr FMJ, 3.9gr ASP, 134.5 PF) are pretty clean out of a 4.6" barrel.
