G'day guys

I have a weather warrior 1:10" twist .308 that has been glass bedded, and had a new rifle basix trigger installed. I have a load for 150gn TSX that shoot sub .5" MoA. But i'm having trouble with the sierra gamekings in both 150gn and 165gn.. On the topic of not shooting it sprays 168gn Nosler BT's all over the place...

Has anyone got a starting point load for?? I understand that your pet load won't mean it will shoot in my gun but it gives me a ball park to play in...

Thanks in advance....

greatdane
