If you want legendary performance, devastating penetration, huge exit holes and a massive blood trail to track, then attach and launch the Maxx! The cutting diameter is a 1/4" longer than the original Spitfire for a full 1-3/4". The slicing starts at impact with a cut-on-contact point. The serious butchery begins as the .030"-thick Diamize® stainless steel blades open for maximum devastation. A microgrooved ferrule reduces weight and air resistance. Field-point accuracy. Offset blades. No O-rings or rubber bands. Per 3. Cutting diameter: 1-3/4". Weight: 100-grain.
