I tried 8 different powders, & settled on 90.8 grains of 5010 pulldown powder from www.gibrass.com.
They're not far from me, so if I have it picked up, it's only $4.00 per pound!!!
That load chronos at 3,360fps from the 30" Kreiger with an ES of 21. FWIW: I took 20th overall in the Wimbledon Cup at Camp Perry with that load & rifle. Oh, I do like the Nightforce on it too! [img]images/icons/smile.gif[/img]
