Am trying to find a load that works in a new GP 100 four inch barrel.
Am using 125 grain TMJ (West Coast Bullets) and Unique powder.
Have three loads: 7.0 grains; 8.0 grains; 9.0 grains.
Speer says 9.1 grains Unique is max. Lyman says 9.7.
Why the difference? If Speer is correct, then my 9.0 grain load is near max. I don't like shooting near max but with the strength of the Ruger I don't figure a box will hurt.
Any suggestions?
BTW, my earlier loads of around 7.0 grains were all over the paper.
