"Plumper" returned fire, but being armed primarily with carronades, was outranged. With the advantage of height, Glyndwr's archers outranged Mortimer's (themselves armed with longbows). It substantially outranged the M1 gun, rendering it obsolete. It outranged all traditional smooth bore muzzle loading guns, and was far more accurate. These outranged and outpunched the much lighter 32-pounders of "Rattler". The Mk 61 would be outranged, under armed and under protected to face today's rivals.
