I'm going on a elk huntSept 1standhave always used Muzzy 100 grain heads. The guide prefers cut on contact broadheads but will let you use chiesel type heads. Should I change to a cut on contactwith the same blade and body style as muzzys only with a cut on contact head this close to the hunt? Never, ever had a problem with Muzzys but then again I've never been elk hunting either.Anyone have pros and cons of cut on contact's?
