SuperPerformance & 7 Saum
I shot some test loads of 168 gr. Bergers and Hodgon SuperPerformance powder today with positive results. I don"t have a chrono currently so I don't know the velocity but the accuracy at 100 meters was there. Tested to 60.5 grs. and showed no pressure signs. I will bump up the powder charge and see what happens next range visit. I also tested some RL 17 loads and those were a bust.
Anyone else play with the SuperPerformance in their short magnum and what was your results ?
