I have a Horton and I use Spitfire 100 gr. Mechanicals. I have killed several deer with these broadheads but I "Only" use mechanicals because Horton in "General" shoots very poor groups with fixed blades. There are a "Few" Hortons that will shoot fixed blades well but not "Many" !!! If I had a crossbow that "Was" able to shoot consistant groups with a fixed blade I woulduse a Muzzy or a Thunderhead that would go thru bone better. If you have a crossbow now that shoots fixed blades well (consistent tight groups) don't switch. The fixed blade is "More" forgiving if you hit "Bone" !!! Sincerely, Deerme
