4 shot drill w/ reload @ 25 yards

Doing some testing with 10" SBR in .223 (wifey built this with a .223 wylde barrel) - 4 shots @ 2 x 6 inch plates @ 25 yards.
(the "16" comment at the end is total seconds I took to do the drill.
some safety notes :
This SBR is registered and tax stamped.
I'm using frangible ammo (do NOT shoot steel this close with regular rifle ammo)
magazines are 20 rounds.
