NEED ADVICE 100 GRAIN SPITFIRES FOR ELK?????? ANY OPINONS.

I' ev never hunted Elk,they work great for whitetail.

you may try posting this on the bowhunting page , more people read that.

NO NO NO NO NO NO!!!!!!!

Use a fixed blade head. The spitfires are harder to open then most of the other mechanicals out there any way. Mechanicals just use up too much energy in opening especially ir the elk is 30 yards away. You will need all the energy pushing the arrow through and not using it in opening the blades.

Elk are about three times as thick as your average whitetail deer and have much bigger and heavier bones than whitetails do also. Elk can travel a long ways before they die and a good entrance hole and exit hole is paramount. You still may not get the exit hole and if that is the case then the entrance hole is even more of a priority for you in finding the elk.

You will be much better off with a fixed blade head!!!!!!

First you really need to tell us about your set-up, arrow, KE and max distance you may shoot. But unless have a real high KE set-up and are keeping your shots real close(under 30 yards), and are Superman, I wouldn' t even consider it! Go fixed!

Not enough information about whether or not you CAN use mechs for Elk......there are some I personally would use confidently, but I' ll tell you this much about the Spitfires: My Set-up is generating 80+ft lbs of KE and I wouldn' t use Spitfires on Elk. They' re strong and sharp heads, but slow opening and a bit to long on the cutting diameter IMO for even the more radical set-ups.

I agree, need more info. You exact Kinetic energy figure is best, but if you have your bow make and model, draw weight and draw length along with your arrow syle I can make a pretty good " guess" . I agree with the others however the spitfires are fine mechanical heads, but they do open slower than most, and with the 1 1/2" cut they won' t penetrate as well as a smaller head. I would personaly prefer a fixed blade head for elk, but I have tested a few mechanicals that will work pretty well if you have the right setup and a well tuned bow.

Same here on all above counts. Even with generous amounts of KE Spitfires would not be my first choice of mechanicals to use on an animal the size of an Elk. I would prefer an exposed blade broadhead, generally speaking, but would suggest Steelheads or Naildrivers if a setup had enough KE for their use.
