I have never used a Mechanical broad head on any big game, only turkeys. For turkeys there is nothing even close to the rage mechanical head. It's just devastating in every way and absolutely as accurate as a field point.

I have a weird curiosity of mechanicals, maybe because of my engineering education or simply that some seem like a brilliant design idea. However several I have looked over or fooled with are not what I would call good engineering, rather very good marketing!

The rage for example is a great idea, but I think it has a flaw in that the blades just don't remain closed 100% before the shot. Except for that one problem I think they are pretty darn good. That one problem however would be a deal breaker for me. Now they have come up with a design that incorporates a little sacrificial plastic sleeve to keep the blades closed. I have used these on the turkey broad heads and they are 100% flawless so far. As well as when used on my sheep.

I have corsican sheep on my farm, I sell off about a 12 a year, of those about 8-10 I sell skinned and gutted to local farm workers for some type of feast they have seasonally. I have shot all these this year with mechanical heads to verify operation and function. My Switchback shoots at 63-64 lbs. 29" draw. 440 grain arrows. With the Slick tricks in the past the arrows zip through these 125lb sheep and land well beyond them.

With the several mechanicals I tried they stick out the other side about 1/2 the time and exit about half the time. The angle being the likely difference. The death of the animal is notably and decisively faster with the 2" Rage and NAP broad heads then the slick trick. The gash sliced through them is wicked to say the least. The Grim Reaper was another great Mechanical but it was the least likely to exit, much like the shwacker. However the entry hole is a bloody disaster that is more impressive then any bullet could be.

Speaking of the NAP "rage copy" it's a bit complicated at first because the blades are so tight in the ferrule that it seems as if they would never open and would penetrate straight through without opening up. It's not impossible to get them to open but you cannot do it easily with your fingers by trying to. The risk of slipping and slicing yourself is quite high anyway.

I set up a test of these to see how they would open before I shot a sheep. They opened completely on a terry cloth rag duct taped tightly across a 5 gallon bucket. The blades opened slicing a 2" gash through the soft terry cloth rag and then out the bottom of the bucket as well! On every single sheep they sliced 2" in and out of them with death in seconds, as fast as using my .223 with Vmax bullets works on them.

Anyone handling these NAP mechanicals is sure to question the difficulty opening them up. I assure you they snap right open with 100% flawless precision..... so far anyway. The Rage always open as well, unfortunately they may open too easy without the plastic collar. Using the collar they have never failed me.

I have shot two sheep quartering away deliberately behind the last rib at 25-30 yards. Both the NAP and the rage sliced 2" wide gashes clean through exiting behind the shoulder opposite side. The Grim Reaper worked just as well, but stick into the bone of the front leg not going clean through. Just the luck of the sheeps stride at the shot.

I have wacked, dropped, smacked and tried every reasonable means to get the NAP to open other then shooting it without success. That is very comforting. It's clear to me that the folks that developed these used them on game and figured out the blade tension needed to hold them, and then to deploy them. At first look you will think they cannot open up upon impact, but they do!

In any case they shoot like field points. I have a practice tip with the ones I got for test. I forget it's in the pipe stand when I shoot and practice with it right along with my field points on my 3D targets. It's surprising when I find they hit the same as the field points every time. Even out to 50 yards!

I'm not sure if I would use them on big game, although for turkeys and probably small game and even deer they are likely just fine. They have been 100% flawless on my Sheep, close in size to deer, but build much heavier then deer.

I understand the debate between mechanicals and fixed blade heads. I definitely fall on the side of the fixed blades at this moment. However the writing in on the wall as they say. The NAP and the rage are darn good and dependable. Not to mention field point accurate and they make astonishing huge gashes entry and exit.

The one mechanical I was disappointed with that gets a lot of press was the Schwacker. Those only make a small entry and penetrate the worst of them all. If they exit they make a huge 2" hole, but the entry is just a little 1/2" opening. I cannot see a shred of a reason for why anyone would want this small entry design?

Small entry, with shallow penetration only getting you the big 2" exit for great blood flow ***if they exit. If it does not make a 2" entry and a 2" exit then whats the point of using a mechanical?

Anyway, In closing on this rambling commentary on my current opinions of mechanicals. The commercial where Chuck Adams says " it's like throwing an Axe through and animal" Well that is a very well stated observation. When you see that 2" hole through the chest of an animal it does look like an axe must have passed through it!

Here is a photo of the NAP practice tip. It's clearly just as accurate as a field point!

Thanks for the reviews! Your testing setup seems perfect for real world hunting with those goats.
I've always worried about mechs but your write up certainly inspires confidence in them.

Not all of them. Several were not at all good.

The NAP kill zone and the rage hypodermic as well as the rage turkey heads I felt did the job great. The grim reaper as also quite good.

Nothing else I've fooled with impressed me yet. Most were rubbish based only in marketing. Like the shwacker was poor at best.

Have you tried the Ulmer Edge?

I did this week on a bull at 54 yards. The only reason I used it was because it was my second arrow and I thought I already put the first one through him (125gr Shuttle T). Turned out a ranging error on the first arrow left my arrow short so no first hit. The Ulmer arrow blew right through him on a quartering away shot (right side), and based on the blood I would have to say liver and at least one lung. The wound apparently sealed up because the last blood was a large pool and then......nothing. The game warden even had a tracking dog, and we searched another 4 hours with him with no success after already searching 5 hours after the last blood. Lots of blood down before that, then nothing. Even the game warden was shaking his head at the amount of blood down and no animal. Without finding him, hard to say what happened other than the wound sealed up.

Two years ago shot a large bull with the 125gr NAP Spitfire on a very steep slope, and it was like someone dumped 5 buckets of blood in 5 different spots that poured down the hill. Pretty sure he bled out quickly and just fell over.

I have not used it.
Not readily available here.
The only one I handled did not seem like the blades stayed in the cutting position. They tilted back and forth. I see their marketing claims that this is to tilt around bones. ??? The NAP just sliced through ribs. If your hitting bigger bones then ribs the broad head is not the problem.

The manufacturer should not be solving this problem by making pivoting blades. I prefer the blades locked open and driven through whatever is in the way.

Actually the blades do lock open but they do pivot around bone. they also have a rear cutting edge just in case you do not get a complete pass through. working in an archery shop we constantly try out new products and test them in many different ways more than what they were meant to be used in. for our results the Ulmer Edge has been one of the best flying broadheads and has given us a very consistent results. the rage hypodermic broadheads have also proved extremely well

Nap Spitfire is my go to head, with the Thuunderhead 125 close behind. More blood and faster kills. I used the 125 last week and watched the bull tip over.

I am a fixed blade guy but my buddy had given me some Ulmer edges last spring. Practiced with them in practice mode with the blades locked in and they flew identical to my FP past 80 yards. So I figured I would keep 2 in my quiver, along with my normal 3 TT Terminal T's.

While hunting elk about 10 days ago we ran into a WT feeding at first light on side of a river valley. I closed the distance quickly but ran out of cover. After waiting a while I decided to shoot the WT at 77 yards with the ulmer edge. It was quartering away, no wind, and had no idea I was there. The arrow flew like a dart perfectly behind the front shoulder coming out the chest thru a lung and clipping the top of the heart artery. WT Ran in a circle painting the ground a bright red (think Quentin Tarantino movie) and 10 seconds on the ground in nearly the same spot I shoot it at. All this was in view of me and my hunting buddy. The Arrow recovered and can be used again. No damage to shaft or the Elmer Edge although I will have to replace the blades as putting them back into shooting position took more effort than it should(could not see any bend in the blades but its gotta be their).

I am still a fixed blade guy but this has given me confidence in using the Ulmer edge on elk this year if Its windy and I am worried about planning or for second shot if needed.

My favorite MBH is still the Vortex 125 gr. steel - it's a shame they do not make them anymore.

You need to use the tool provided in the package to get ulmers closed.

Tool? Mine didn't come with a tool.......nor did they come with very good instructions on using in "practice mode". Seems like you need an extra screw or something to put in the hole to keep them from opening????????

There are some things many folks don't click with right away using a mechanical head. I have shot these few different models a ton the last few weeks. I've fooled with them at several levels. Took them all apart checked blade sharpness, yeah even had stitches put into my hand because of this relentless desire to see how things work. Nearly ruined my bear season with the damage to my fingers. I had be sure I understood all I could about the designs.

The one common thing about mechanical heads is the power of delivery. A 60lb draw with 350-380grain arrows is not enough. I am not sure if there is a spec on this from the manufactures but from all the sheep I have now killed I can say I would NEVER use a delivery system this light. I had too many arrows not make a clean pass though on these 90-125lb sheep.

Moving up to 60 plus to say 65lb and 440 grain arrows will work good to about 30-35 yards. However if you really want to see what a mechanical can do, 70 plus ( I used 74lbs) and a 500 plus grain arrow will knock your socks off. With this level of power you can see the blood explode from the entry hole at impact.

The weak link or the functional limit becomes the velocity to get extraordinary performance and not destroy the blades at impact. The long blades will twist and bend.

The next issue I have to get my head around is that the big advantage we all believe is a 2" slice going in and coming out. If it's only and entry hole without an exit then did it help? Shot at a downward angle from a tree puts the hole high in the body. Blood flow does not always flow out good from a high entry and no exit.

The logical thought is go down to something like the ulmer edge to 1.5" so with a lower power delivery system can get a pass through. Even with this 1.5" size there is, or at least to me seems to be a penetration reduction. My best thought on this is that it's like a parachute opening at impact. With the 1.5" cut on this design, the blades swivel with the possibility that one blade rides against the ferrule and only one is deployed to cut.

More important is that dropping to a mechanical of only 1.5" with 2 blades gets you 1/4" over a head like the slick trick 1-1/4" cut head, but that fixed blade model has 4 blades. This fixed blade will out penetrate a mechanical from what I have seen 100% of the time. Working perfectly with 60lb draw and 400 grain arrows.

The time spent was great fun, except for the emergency room. I feel a lot better about having this conversation with my hunters now. Rather then just bluntly saying mechanicals are bad. I don't feel mechanicals are bad. I do think you need to put a lot of thought into the delivery system. These designs need some serious power to make them perform with stunning results.

There was a time that I felt mechanicals would eventually take over ( down the road a ways yet) when the designs were more refined and dependable. Now I'm not so sure. There is a need to drive them with high powered bows to get the most out of them. I would not be confident shooting less then 60 pounds and a sub 400 grain arrow.

You guys decide, I'll keep using them on turkeys. There is no broadhead better then a 2" mechanical for turkeys.

You could build a force/penetration machine with some thompson slides, a load cell, and an x/y chart recorder and graph the force required to fully penetrate a uniform density mtl for a variety of heads. You'd then be able to compare any and all heads to one another. You would also know if/which mechanical blade/point systems penetrate easier than some fixed versions. If I was going to design a broadhead that's the first thing I'd do.

Well to each his own, it makes no sense through understanding of aerodynamics and physics that a fixed blade broadhead would fly better than a mechanical broadhead. however yes a larger blade does take more force to push through an object. also a pivoting BladeSystem through any understanding of common physics would push on both sides not just one applying in the equal amount of force causing both blades to be open until 1 met a firm object which pushed it close causing the other blade to overcompensate until that object was passed. for what my experience is a ulmer edge blew through a javelina at 35 yards broke two ribs and a shoulder bone shattering the shoulder getting a complete pass through at 63lbs using a ,360ish gr arrow. I'm now shooting a slightly heavier set up with even more devastating results. I like and will use TT Shuttle t locks as well but for long distances and ultimate damage mechanical is hard to beat.
