I've had good results with 6.0 Power Pistol and several different 115 grain JHP at 1.08 to 1.09 OAL. I once did an experiment with new Lapua, Lapua once fired and mixed range brass to see what difference it would make. Strangely, the mixed range brass shot best. Another couple of loads that have shot well with 115 grain bullets in several different guns are 4.5 grains of Bullseye and 6.1 grains of WSF. The WSF load is likely +P and is the one I did the brass experiment with.
