Quite a few 50cal and even 45cal ML loads are already the equivalent of a 45/70 single shot in FPE and or FPS. Mine happens to hit much harder if i choose.
Our minimum is a 40cal bore. It mentions nothing about the projectile other than sabots are allowed. A 40cal 200gr SST shot sabotless at 2700fps + is equal to or better than many CFs within typical hunting ranges.
You want a crazy range ML, look at Swinglocks 416. It will equal nearly any 416 CF on the market in FPS.
