    So by your calculations the bullet probably shouldn’t have fragged from an 18 inch barrel at 410. 20 inch barrels were not used as SDM-R. Nobody I am aware of was using 20in using Mk262. Story sounded a little suspicious. Anyway, MK262 is a great round but There are better rounds now.

    The SDM-R absolutely uses a 20” barrel.
