I had the pleasure a year ago of evaluating the all-new Rocky Mountain Warhead mechanical broadhead.   In just a year Barrie Archery has improved this lethal and innovative broadhead. 'Lethal' -  Webster defines as pertaining to, causing or capable of causing death.  I believe that is a pretty good definition for Rocky Mountain's new Warhead 100 broadhead.  Innovative because it can be used as either a fixed or expandable model broadhead. 

This is made possible by utilizing either of two replacement cartridges featuring 3 .030" stainless steel blades that are razor sharp.  It allows the archer to use the best blade under different hunting conditions, mechanical or fixed.  For example, pronghorn hunting where longer shots combined with wind conditions may be more suitable for a mechanical to help reduce planning. To change from the fixed model, it's a simple matter to switch the cartridges to make the Warhead Expandable model. When the fixed blade model is preferred, you just change out to the fixed cartridge. Versatile and lethal?

To switch or replace cartridges, remove the broadhead from the arrow, slide the old cartridge off, align the new cartridge blades with the ferrule slots and slide on.  The ferrule slots align the blades perfectly with the tri-cut tip allowing for great penetration.  Replace the broadhead onto the arrow and you are ready to go.  The three blades are held firmly in the cartridge so you don't have to fumble with changing individual blades or setscrews.  If using the expandable cartridge slide the rubber band, which holds the blades in the closed position, onto the blades before screwing into the arrow.
As mentioned earlier penetration is not a problem due to the razor sharp blades aligning with the Tri-Cut head.  Tests were performed on ½" pine board and ¾" plywood at 15 feet.  The heads were mounted on 28.75" Easton ACC arrows and shot from a 65 pound compound bow. Both heads completely cut through the ½" pine board, actually mirroring each other and splitting the 8 by 18-inch board in two.  Penetration on the thick and tough 10 by 36-inch plywood board showed somewhat different results. 
The Warhead 100 fixed blade almost exited the board with just the last part of the blades resting in the board.  The mechanical blades deployed and were just barely visible.  Both shots showed me the effectiveness of the tri-cut head.  Exit holes on both boards displayed similar splintering results.  I believe this shows the bone splintering capabilities this head is designed to do.  This comparison truly shows the difference on a plain pine board that represents soft tissue and ribs versus the harder and thicker plywood,

 which is a tough representation of thick, hard bone. 

Accuracy test were completed on a 20 yard course and consisted of four -  three arrow groups alternating between field points, mechanical and fixed blade.  When the shooting was done you couldn't tell the difference in any of the groupings.  I would put this broadhead, fixed or mechanical, in the TOP TWO rankings of every broadhead that I have ever tested or evaluated for accuracy when compared to field points.  That is a lot of broadheads in my 20 plus years of bowhunting

Conclusions

Design 4.5 of 5
§ The design was modified slightly from a year ago.  A little shorter but still a great all around broadhead when you can combine either a fixed or mechanical design.  The only reason for not giving a perfect score is I believe the blade tolerances could have been a little tighter when screwed onto the arrow shaft.

Toughness 4 of 5
§ With a blade thickness of 0.30" the blades survived multiple shots into and through tough materials.  Like I stated a year ago, the Tri-Cut head is a plus and is designed to smash through bone.

Accuracy 5 of 5
§ Field points, fixed blade or mechanical, I could tell no difference with the results. 

Sharpness 4 of 5
§ The blades on either model will have no problem on even the toughest of big game.  A well-placed shot should result in a complete passthrough.  Blades come razor sharp and ready for action.

Penetration 4 of 5
§ Even though the ferrule combined with the head is amongst the largest in the industry I believe with the Tri-Cut tip does an excellent job of clearing the way.  This combined with the sharpness of the blades delivers above average penetration.

So if you are undecided about what type of broadhead to use, fixed or mechanical, you can now have the best of both worlds with the Rocky Mountain Warhead 100 by Barrie Archery.
