Loads using IMR Trail Boss in 416 Rem ?

Has anyone tried Trailboss with 350gr. bullets in 416 rem. mag.

No, but I have used TrailBoss in the 458 Win Mag, 500 S&W Mag, 470 Capstick, 45-70 and 416 Rigby. It works really well with top loads around 1250 fps. It is impossible to overload any cartridge with TrailBoss. Typical pressures are in the 15,000 CUP range.

Fill the case to the base of the bullet. This is the max load. Starting load is 30% less powder. This is straight from Mike Daley at Hodgdon/IMR.
