Man this tape debate always cracks me up! Has anyone ever seen something bad happen to point of impact from taping a barrel? Who has seen what happens when you fire a rifle with water or even a small vegetation obstruction down the barrel? I'll tell you what happens - at best a shot off target, at worst permanent damage to the barrel. I conducted extensive tests years ago to prove this, but it still keeps cropping up. We tape all our muzzles/brakes when we take them out of the gun rack before putting them in gun bags. You wanna see how much rubbish hops up into the muzzle as you run a rifle into a gun, even one you think is clean. And then there's rain, snow, leaves, sticks, dirt, etc etc. The tape is long gone before the bullet gets there!
If you refuse to tape your hunting rifle's muzzles - hey, its no skin off my nose - its your barrel!!
