For starters, I am shooting 30gr Bergers with 29.5grs of W748 behind them. Running around 3900fps. It is a shooter. I sighted it in at 50 and moved to 150 and had them stacking up. I think it was luck only. The wind was crazy. I was only shooting 3 shot groups and 2 were on top of each other and one would fly to about 3/4.I am shooting up some rounds I have laying around. I am waiting for Old Turtle to give me some of his W748 loads he used to load. I have 32gr vmax, 39gr BKs and 34gr Varmint Nightmares that I am going to load.
