Do mechanical heads work for crossbows?

Do any of the mechanical heads work with crossbows? If so which one's, does Swhacker work?

 

Can't see why they wouldn't.... I use Muzzy 3 blades with mine, cheap and tough.

 

Because the added dw makes them open in flight. Also Muzzy does not make mechanical broadheads. Either you are mistaken or you bought fake/ knock off merchandise.

 

my Muzzy's are fixed blade, that wasn't my point...

I think I used some NAP mechanicals when I first got my cross bow, but honestly don't remember the outcome. Really don't have a way to check either...

 

You can tell when they open in flight, they dont fly the same as the practice heads.
EDIT:
A quick search and I cam up with NAP Spitfire 3 Blades or Wasp Jak-Hammer SST.
I shoot the fixed blade version of the Wasp.

 

I use the new 2010 Grim Reapers in my crossbow.They work just fine.

 

my girlfriends shoots the 3 bladed rage out of her ten point and she is 2 for 2, recovery less than 60 yds.... a doe and 140 class 9pt...good luck with your choice....the year before that she used 100gr muzzy
