I have some 780, which I got for loading 160 NPs in my .270 because it gives top velocities and even the starting load is plenty fast enough for almost anything. The 780 data for the .243 also looks impressive, but the stuff is pretty much impossible to find, so I'm saving it for the .270 loads. You never know when a moose or griz will pop up in WV using one of those trans- continental Bigfoot tunnels that Art Bell used to talk about!
