I load the 300 grain xtp for my Dan Wesson 44 magnum (8 3\8" barrel) revolver with a maximum charge of H110 crimped at 1.600" cartridge length as per Hornadys recipe for deer hunting. I get good velocity (1125fps) and decent groups (2-3") at 50yds but keep wondering if I used the other cannalure if I would see any appreciable improvement in accuracy or velocity. Does anyone know if this may be worth pursuing and if so where to find load data for this cartridge length? The second cannalure is about .160" farther down the bullet.
