these are great broadheads i used them the first year that they came out and all i did was buy them and some gold tip arrows i took the heads out of their package and put them on i did not balance them in any way i screwed them on and started shooting at the range first of course i was in love after the first six shots that year i shot a nice buck with them... if you have not yet shot one with them just wait until you do the blood trail is amazing i could follow it from my treestand for the first 15 yards...
when u get to the deer the hole they leave is something else that is amazing


i have used them ever since and had nothing but great results on every deer or critter i used them on i use the 4 blade 100 garin hope this was some help and have fun cause i know you will.....
happy hunting and straight shooting.. browning_xcellerator
