I have decided that weekends are for shooting my own stuff. I can do work shooting on weekdays. Sunday saw another hundred rounds of TulAmmo sent downrange through the Gen3 19.
I started out shooting at the upper target box at seven yards, at about the pace I'd use on the 3x5 in a FAST...call it .6 or .7-ish splits. Then I backed it out to ten yards and shot the bulk of the ammo at the lower target, trying to push speed at ten. There were no malfunctions, and the gun now has 4,144 rounds through it.
