If I am not mistaken, the latest Hodgdon load data manual shows Autocomp producing the highest velocities of any of their powders
for the lighter bullet weights so that definitely warrants looking into since I am distinctly a
Hodgdon manual-----MAX Charges--------
> 135gr Autocomp 9.5gr 1476fps 34,500 psi is a Winchester powder
> 155gr Autocomp 8.9gr 1362fps 35,700 psi is a Winchester powder
> 155gr IMR 800-X 9.8gr 1350fps 30,000 psi
> 180gr Longshot 9.5gr 1287fps 34,800 psi
> 200gr Longshot 8.2gr 1172fps 35,000 psi
Their description on their website is puzzling
however as all they talk about is design for
competition shooters with something about
more gas for compensators. That is phony
hogwash as the mass of the gas cannot exceed
the mass of the powder.
Simple as picking a heavier powder load if you
want a greater amount of gas to act on the
compensator. Of course you would
not overlook the pressures produced by those
heavier powder charges. I think AA#9 would
be best for compensators as I think those are
the heaviest powder charges I have seen.
