Fiocchi, AE, and home rolled 40gr VMAX data

[towerofpower93]

Collected some velocity data a couple days ago after getting the Fiocchi 40gr FMJ from Battle Hawk Armory the other week. 10rd groups except for the AE 40gr FMJ in the SBR’d PS90 which only had 7rds. Wasn’t planning to put it past the LabRadar, but I had a half full mag in the Rock and moved the others over to the PS90 after shooting the pistol.

PS90 SBR suppressed with Saker 556K ASR
