since i have no idea on how those targets were shot. IE, ransom rest, ganst style, upside down -between the legs, ect, it makes no dif to me on what the target has on it.
where i make my decision is at the range with real ammo and after a few rounds to get familiar with the gun. I know how well or bad i can shoot and judge the target then. if i have a bud w/me, i let him/her have a go at it.
imo, most guns out shoot the shooter.
