I'll have to look up the exact numbers from the last time I chronographed it. Out of my 18" Noveske SPR barrel I believe it was around 2550-2600. Like I said, not nearly as fast as real MK262, which clocks in around 2700 in the same barrel. You'll get a tad closer going up to max load, whichi s 23.5 gr TAC according to the Nosler data.
