[QUOTE="Lefty7mmstw, post: 993962, member: 48043"] the 7stw is dumbed down 1,000 psi from the 7roy and 7rum pressure wise; not much but it is dumbed down ( gotta love that the 7rem is dumbed down 4,000 psi). It also has a bit less freebore than the roy.... the roy is spec'd at .378" freebore.... the 7stw is spec'd at .206" freebore. Either way you've got a good bit of run to the lands. An aside here, the 7rum has .632" of freebore; if more freebore is making so much more speed, why hasn't the 7rum attained warp speed yet?
