How much, and how it would translate to the current crop of bullets on a LR-FC target... is a good question.
When I ran the numbers on paper it appears to have 10" less wind drift @ 1000 yards (5mph crosswind) over the 175 SMK's I've been shooting IF I can push them as hard as the 175's. I tried some 185's this week and I'm seeing the right velocity without any "usual" pressure signs, haven't measured the cases as of yet to see if their stretching. Next test will be to see how well they group @ 300 yards.
