I finally had a chance to get out and start testing some loads. I'm using Lapua brass and CCI BR2 primers on all loads tested. Rifle is a Ruger 77 with a 22 inch barrel. Chronograph is a MagnetoSpeed V3.
120 NBT, 47 grains of H4350, 3.05 COL 2789 FPS AVG
140 Partition, 44.5 grains of H4350, 3.05 COL 2577 FPS AVG
155 Lapua Mega, 42 grains of HV100, 2.95 COL 2452 FPS AVG
All of them shot right about 1 MOA at 100 yards so good enough for hunting. I'm going to play a little more with the Partitions. I'd like to get around 2650 FPS. I'll probably load up some 140 Core-Lokts next time too.
Working loads for a free range Axis hunt June 1st.
