Re: Is there a formula for powders slower than listed in the manual??
I hadn't considered that H-BAR. I may just give them a call and ask if THEY have some sort of formula they use for testing.
Thanks for the info guys,..I will be trying the RL25, Retumbo, 7828 and H1000 to see how fast I can push these 140's and still maintain sub .5moa groups. I'll post any results as load workup takes place.
You try to get closer to the target,..and I keep trying to get further away.
