Yes, I’d be curious to know what kind of firearm training he’s had.
I heard that he and his bud went to a firing range to practice. Other than that....nothing.
Apparently he just shot it some at the range with his friend. His level of firearms knowledge is indeterminate — remember his “I don’t know, a bullet is a bullet” in response to Binger’s absurd line of questions about the difference between hollow point bullets (which according to Binger just explode inside the target) and FMJ bullets.
I agree with the article - his firearms handling, and trigger/muzzle discipline was amazing.
