Bought a set of these heads the other day and got around to shooting them today. As you can see the blades are offset. The head flies exactly like field points all the way out to 40 yards. I have one concern and I would like some input. When going in this target the head would twist into the target. When pulling out of the target it doesnt pull out the same as the entry hole. Im wondering if this will affect penetration into an animal being that it will continue to turn after entering? Just thought I would get some intake from the wealth of knowledge sitting around this board. Either way I think i may try them saturday and I will let you guys know what happens.
