My first post here so a little back ground. Shooting cowboy action, .45LC, both in revolver and rifle. Other then the possible problems that might arise with the perfection of the bullets, is there any concerns in regards to damage to the firearms if zinks is present? As far as shooting goes, we're just trying to hit a car door at 10 yards or so! Minor bulet flaws sould not be a problem as far as accuracy goes. All for now. Appriciate the help.
