I am not trying to start troble, just giving results. I am shooting a Parker feather mag 61 lbs. at 27" with Easton epic arrows that weigh 344 grains with a 100 gr. head. I settled on the Rocket steel head 100 mechanical with a lot of reservations after getting a lot of good advice on this site. I had a doe come in 30 min. after my 10 year old missed a big doe at 20 yards.(he shot right under her chest but used his 10 yard pin instead of his 20). The doe was about 25 yards and came in fast. I had to bleat with my mouth to get her to stop. I used my 20 yard pin and thought I had missed but my son said I hit her. The deer trouted about 50 yards, stopped and fell over. There was a huge hole where the head came out. The arrow went thru the dear like a rocket (pun intended)and I thought I had missed it. I hit a little low due to the deer being about 26 yds. and I used my 20 yard pin. I think this head gave great results out of my under powered bow but with a bad hit, I could have had a problem, maybe? Has anyone else had any bad or good results with this head. As of right now, this is going to be my first choice for a head.Don
