I have been shooting NAP Spitfires with GREAT results. I recently took a 150-pound Capybara in Argentina with a 125-grain Spitfire. Pass through shot. Blades fully opened. BIG hole. I also trusted a Spitfire to take two Blackbuck Antelopes in Argentina.

I would have no qualms at all about taking a Spitfire to Africa to take some of the smaller deer-sized plains game there.

I have also taken several whitetails with both a Shockwave and a Spitfire with excellent results.

However, I will say that I would not use expandables on such big animals as elk or larger. Fixed blade cut-on-impact is the way to go when you get into the BIG game like Elk, Moose, Buffalo, etc. in my opinion.

Not only have I been impressed with the Spitfire broadhead's performance, but also with it's durability. It's a tough head for a mechanical. Clean it up a bit, swap out the blades, and it's ready to go again in most instances.

The same with the Thunderhead. I have found them to be very durable, very reliable, and very SHARP! Great broadh heads!
