We tested the tape on the barrel theory. It didn't make a difference. We used from scotch tape, electrical tape, masking tape, even duct tape. All shots were dead nuts on. We used rifles, slugguns, muzzle loaders and even my single shot pistols. Didn't matter. We did it for the rain concept and snow as well.
