39.5 of 3031 is extremely accurate with a couple of 168 gr. match type bullets in FC and LC brass. This is in five of five rifles tried.
Up to nine of nine now.
If you've been shooting Federal 168 gr. match ammo and you still have that heavy brass, you owe it to yourself to try 39 or 39.5 gr. of IMR3031 under a 168 in it.
I'm getting ready to try this in some Lapua brass which, if I'm not mistaken, should yield similar results to the fed brass. well ... similar from the standpoint of volume/brass thickness. I expect the lapua brass to last longer.
although to be fair, the federal brass has held up pretty well so far. I'm not pushing it to the gills, though
