The 20 gauge is going to shoot a heavier slug 260 grains +/- at 1600 fps or more.
The .50 cal. MLer is going to shoot a 173 grain .490 round ball at 1600-1900 fps depending on the powder charge.
The lighter round ball will shed its velocity more quickly than the heavier slug.
The edge goes to the 20 gauge slug gun.
