Mk 262 - Military usage

[indianalex01]

I just ran a quick ballistic calculator for M262 out of a 20 inch barrel. Its known to fragment reliably down to 1900 FPS and it hits 1900 FPS right at about 400 meters.

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.
