I've shot them for the past 4 years, going on 5. I have killed 10 or 11 deer with them and have never had one fail me. Great entry holes, TREMENDOUS exit holes, blood like you poured it out of a bucket, and I just shoot a Reflex Xtreme Powerflex.
I don't know if image station works here or not but here is a pic of one of the first one's I shot with the spitfires..
The shoulder shot it the first shot, he didn't go 15 yds then bedded down. I got impatient and shot him again in the head. Looking back , I should have waited another 2 minutes and it would have saved me an arrow.
BTW- two years ago I killed 3 deer with the same broadhead, re-sharpening in between kills. I also killed a big 8 pt on a severe quartering towards angle, the spitfire entered exactly where it hit and passed thru the front shoulder and out just in front of the hind leg.
Can you tell I am sold on them?
