Recently looking around the shop I have seen the F-15 broadheads. They looked pretty sweet but I had my doubts. I went onto their website and they are giving them away for nothing more than shipping and handling. For me it ended up being $4.95. Because they are so expensive I decided to do this to see if they were worth it. I am pleased to say I feel they have lived up to the hype. I shot the new F-15 alongside my Muzzys, which are great broadheads and have done some serious damage on bulls, and I am truly impressed. I shot out to 50 yds, my dang 60 yd pin broke off I'm the middle of shooting, and the flight was perfect. I shot the F-15 and then three field points and was grouping at about 4 in at 50 yds. When comparing the F-15 to the Muzzy the F-15 had about three inches more penetration into our new Block and was tearing huge holes through our target. At this point I only saw them available in 100 gr. but this year the F-15 is what will be headed out into the woods with me. I am very pleased!
