It depends on what you asked for out of this work?
Did you want to shoot 3 1/2"?
Did you want to shoot magblend?
That is a nice even pattern for hunting, but is it what you asked for, or even close?
From what i read around here he does good work and has sent multiple chokes out to guys until it is what they want, heck just ask him .
If your good , forget the rest and give them turks the dirt nap.
