[QUOTE="Lefty7mmstw, post: 822326, member: 48043"] The vit data I have is incomplete but with vit 560 ( vit. flyer from 2002) the 7 weatherby tops at 69.8 grains with vit 560. Vit. has no data for the 7stw in my data. The new hornady data for the 7mmstw shows v 165 at 67.3 grains start and 76.5 tops with their 162 grain bullets. Since v 560 is slightly faster than v 165 but the stw has more capacity and equal pressure to the 7 roy I'd start at the top roy charge of 69.8 grains ( or slightly lower) and work to 98-99% or so of the v165 max from the hornady data.
