Have you ever done any long range target shooting?
Just wondering.
140 yards is nothing to a well-practiced shooter using a properly sited and maintained rifle, though suppressors, if he used one, are notorious for throwing trajectory off by millimeters - as in just the amount that saved President Trump from certain death. But I'm going with Antifa dude seeing the counter-snipers moving and let urgency throw his aim off. That and God.
There's a reason I use this variant on my last name.
not over 100 yards.
I did fire a well-sighter Barrett 50 cal last year. dead center.
