Congrat' s man ......that' s awesome !! Tazman is right .......have you practiced with them ???
I tried Steelheads years ago and didn' t like them....... a few observations I made.........

1. They were the only expandable I ever have used that shot differently than my field points. My steelheads shot a little high !

2. I think (by design) they are noisy and 3 out of 3 deer I shot at ducked. Never had another deer duck with any other broadhead with that particular bow set up.

I know plenty of people use them with no trouble ......and many deer are taken with them (I' ve even seen some) but the above..... and the fact that the threads are too short on them , is my experience with them !!

Good luck and way to go.......I would get that deer mounted if I were in your shoes !!
