Yup, LBT designed WFN or LFN style bullets in the .44s, 45/70s, and .50cals., the bigger, heavier and wider meplat the better, hollow pt. versions of the same bullets for deer and smaller game. Minimally, 300grs. in the .44 Mag., 400-500gr. in the 45/70s, and 500-700 in the .50s, cast hard when using top end velocities, cast softer when used at lower vel.
