I expect you are right drache. Why is it that in Iowa centerfire rifles are not allowed anyway? Is Iowa that denseley populated or is there some other reason? I think in some states the thinking was to allow weapons that have a more limited range than rifles so as to prevent accidental hits two miles away on houses and cars and people. I guess we need to make sure the lawmakers make decisions based on good information and not on myths and wivestales. But the high performance muzzleloaders available today will more than likely cause some changes in hunting regulations.
