Well said Stickemup. I' ve tuned bows both ways, strictly group tuned broadheads, and strictly tuned BH' s towards the filedpoints, over the past few years, and guess what, I haven' t failed to kill every deer I' ve shot at the past 5 years, all dead within 60 yards. Absolutely doesn' t matter.
Some folks feel a broadhead should be tuned to the best group, even if it' s coming off the rest tail high, such as many target shooters will do, and others feel it' s best to have the BH' s impact the same as fieldpoints, to ensure they are coming off the rest as straight as possible. I use the first method when using Muzzy' s, and the second when using shockwaves. Probably doesn' t make a damn bit of difference in the real world, but it gives me something to fool with. Like Rack-Attack said, I just don' t feel right without an allen set in hand.[
