The case is very similar to yours; I just happen to like the Rem case design a little better. Anyway H-4831SC worked like a champ in it at 1k; using the 190gr Sierra Mk.... running at a cool 2900 fps and accuracy was outstanding! There are newer powders and a few older ones that offer a few nice surprising pressure curvesÖ. You and powder, have a long ways to go yet, thatís what makes it fun.
Thanks again for the reply and the help. Its nice when people respond to your thread with a answer, but its alot better when someone replies with an answer and also tells you why it is the way it is.
I appreciate it.
