If I can get the 150gn ABLR to fly like I want with good accuracy at 3000 fps I will be happy.

That shouldn't be a problem out of a 26 inch tube with H4831SC. I think nosler list that powder as their most accurate for the 150gn weight class bullets. Velocity looks to be right there where I want it, but to be honest I figured it would be a little higher. I will stop where I find the accuracy node. Hopefully accuracy and desired velocity will be there. If not I'll try something different.
