most at club like spitfires 100 gr.they like idea that the field spitfires shoot same spot as the hunting blade spitfires.they buy them on sale for 26 dollars in feb .

I have several friends that use this or that brand of expandables with excellent results.

My friend shot his deer with a a 2 bladed 125 gr. Rage broadhead out of a Barnett Predator crossbow. The deer fell over within 50 yards.

I shot this buck using grim reapers. (dressed out at 160 lbs) They fly just like my field points and do not open until contact with the deer. The arrow passed thru and I found it 40 yards past the deer I shot. I also put a doe down that a buddy had shot and again had no problem.

Im useing spitfires also! Only shot 1 deer with it,28yd dead center shoulder shot,complete pass thru,and only went 25 yds.

Grim Reaper Xbow model....field point flight and insane blood trails

yeah they work.bows and crossbows are the same princible,they both shoot a aroow forward using kinetic energy.

I'm another satisfied Spitfire guy (Barnett Quad 400).

Yes they do. I use Rage 2" 2 blade. Rage came out with a 1-3/4" two blade this year.
My xbow shoots over 390fps so I have no problems with complete passthroughs with the 2". They leave a hell of a whole in them too.
This is a picture of the buck I shot last year. Rage in the cage.

i shoot muzzy fixed 3 blades in tenpoint. i shot a bear last year ,he went 40yds and died. looked like a garden hose of blood coming out the exit hole. i alway used 3 blades over 2,i just think the hole they make will spread more blood .
