I have never used mechanicals before.. I was very intrigued w/ these bhs and decided to pick up a pack... anyone here have any experience (good or bad) w/ any of the NAP Spitfire products?

Ok.. how about the plain old NAP Spitfires then? Pretty much the same BH... just bigger blades... any experience on the regular SF?

I haven't shot them yet but I just picked up a pack last week also. I tested one through a 6" foam target and it expanded fully through the back, so we'll find out how they work this fall I guess
