Thanks for the feedback, I have shot them for a few years now,killed a little coues buck with them,pass through shot, deer went pretty far, I was surprised,little blood trail. Shot a Bull elk at 17 yards, really nice shot through the heart, no pass through, good thing it was a good shot because there was not one drop of blood to be found, we heard the bull crash but looked for blood to trail since we were in thick country.Shot a big bull this year, hit him just below the shoulder a little forward of the crease, sounded like it hit bone,maybe a rib,found the broke off part of the arrow, not one drop of blood to trail, bet that big bull is dead.I think they fly great ,just to many bad experience with no or tiny blood trails. I am shooting the 3 blades. Maybe use German Kinetic Silver Flames or Steel force premiums, I have heard good things about these 2 blade broadheads.Maybe the wac-um 4 blades are better. Noticed on the heads I have recovered they seem to have tip damage as well. What are the hunters that responded shooting, 3 or 4 blades. Thanks
