RE: Spitfire broadheads
I used spitfire broadheads for the first time last year, releasing 4 arrows, harvesting 4 deer. Every shot was around 18 yards, 2 were pass-throughs, 1 was a quartering away shot, the other was a quartering towards me shot. [The quartering towards me shot isn't a shot I'd recommend, it was on a deer which was wounded during gun season, could hardly walk, I was out hunting for it to end it's suffering] I'm going to continue to use them, they get enough penetration to kill anything. You don't need pass-throughs to harvest deer, I think people get to obsessed with pass-throughs. Get a broadhead you personally have confidence in, if you ask others there are just too many opinions out there. Make a decision and see how they work for you and your set-up.
