I know this is going to stir the pot alittle, but i want to know if the muzzy 125 3 blade is any good. I've been hunting with the 2 blade zwickey heads and don't feel comfortable shooting them past 12 yards. MY old man hunted with them for years and killed many deer, but most were from a tree and at a distance of less than 10 yards. I like hunting from the ground more and with that comes shots 15-20 yards mainly. i bought a pack of 6 and was relativley pleased with the sharpness and accuracy. at 20 yards they were only off maybe an inch, but i shoot instincive, so who really knows. they flew nice compared to the zwickey. i hear people complaining that you won't get good penetration from them. the bow i shoot now is set at 60# and an arrow weighing about 700 grains. if that don't penetrate i don't know what will. but anyhow what about the normal arrow weight about 400 maybe less. will this head still pass through considering a good boiler room hit. any complaints about the muzzy head. I'm not very good at sharpening, so thats why i tried these.
