The circular design of the OCD may seem a bit gimmicky, but the theory makes sense… When you hit a hard bone, it will rotate.The blade does in fact rotate somewhat, so it could potentially rotate around really tough parts of a deer’s anatomy, or other animal.
The circular blade has a 1-inch cutting diameter. The leading blade has 9/16-inch cut. So, the total cut is 1-9/16 inches. So, not huge, but not bad either. It’s a little under 1.6 inches of total cut.
The ferrule of the OCD is made out of 7075 aluminum which, if you’re going to use aluminum, is a really good one to use. That’s stronger than some steels.
The blades are pretty impressive as well. They are made out of 420J2 stainless steel and they are really thick. The circular blade is 0.059 inch thick. It’s a double bevel. And that leading blade is 0.039 inch thick.
As always, I performed this test using my Bowtech SR6 set at 72 pounds, on the comfort setting, with a 27-inch draw. I used Bishop FOC King Arrows, 460 grains. Let’s see how the Blood Therapy OCD performed!
Testing of the Blood Therapy OCD heads
I was eager to put it to the test and see how it goes. I tested the OCD for long distance flight, edge sharpness and retention, for penetration, and for durability.
The OCD flew very well, as I was able to pop a balloon from 70 yards away.
Out-of-the-box sharpness test
In this test, I ran a carbon arrow shaft over the blade (up to five times) to see how many strokes of the arrow the blade could handle and still cut paper.
The Blood Therapy cut paper (barely) after five strokes of the arrow.
In this durability test, I shoot a broadhead into a 22-gauge steel plate to see how it holds up (will shoot up to five times.)
Now, the head did fantastic through three shots. But on the fourth shot, the pen that holds the rotating circular blade in place broke off. The leading blade, however, was in pristine condition. Amazing! It doesn’t even look like it has hit anything. And yet, it cut through the steel plate four times.
The rotating blade did really well also. It got a little bent out of shape, but it did relatively well and much better than I thought it would do. It made it through three times perfectly and then broke on the fourth time.
Here’s the OCD after being shot into the 22-gauge steel plate four times. You can see it made four nice holes. They are relatively small due to its small cutting diameter. It still made a decent wound channel.
In this article, I’m covering a re-test of the 125-grain Annihilator Broadhead.
When I originally tested this broadhead, it performed extremely well in terms of penetration, (i.e., draining a water jug) and in terms of the hole that it produced in a layer of MDF.
It also flew really well out to 50 yards. However, beyond 50 yards, there just seemed to be a drastic drop in velocity, causing an incredible drop in the point of impact.
However, after making a video of that test, I was contacted by some friends who had also tested this broadhead at longer ranges, but did not see the drastic results I had seen.
I then visited with the designers of the Annihilator broadheads at the Archery Trade Association (ATA) show. They also said that their tests had not shown the drastic drop. In fact, they had seen really consistent flight, even at longer ranges. So, I told them I would very gladly test it again.
The backstory to my original test of the Annihilator broadhead
The day of the re-test, it was sub-zero temperatures (with the wind chill). When I re-tested the head, I found that the people I had spoken to were exactly right. It flew extremely well, even at longer ranges.
I realized that in my original test, I had made a two-fold mistake.
My two mistakes
Before I tested the Annihilator broadhead the first time, I was talking to a friend about it. He told me that when he shot it at longer ranges, there was a really large drop due to the wind resistance of that big surface area that they have. And so, that was already in my mind.
So, then when I shot it and tested it and there was a big drop, and I thought, “Oh, this just confirms what my friend had said.” I didn’t retest it or question my test results enough. That was my first mistake. I shouldn’t have had that in my mind.
The second mistake that I made in the initial test is that I had made adjustments to my site tapes and I didn’t take that into consideration when I was testing the Annihilator.
So, I felt really badly. I went back and made the adjustments in my site tapes and… Boom! Dead on!
I feel really badly that I made both of those mistakes, and both of those mistakes adversely affected the reputation of Annihilator (as well as my own reputation for doing a poor job in testing the broadhead).
I want to give a sincere apology to the makers of Annihilator broadheads, to their loyal fans, and especially to those who I turned off from these broadheads after my initial test, because it actually does fly very well even at longer ranges.
So, that’s why I wanted to do a completely new test. I’ve got new test mediums for 2020 that I’m using anyway. So it’s a good way to do those.
The Annihilator broadhead | The specifics
So, let me explain this broadhead just a little bit for those of you that aren’t familiar with it.
However, what I wasn’t understanding was the design of this head has a “scoop” feature to it. So, while it has a small cutting diameter, when it presses through a medium like animal tissue, it actually displaces an incredible amount of it. (Note: As of the publishing of this article, I personally have not tested the Annihilator head on an animal).
So, the hole that it creates, and the tissue that’s displaced, is in theory far greater than if it was just 3 crossblades of 0.91 inches. It has an incredible surface area. (That showed in a test that I had done originally. The Annihilator drained a water jug in record time. It also put a big hole through MDF. And so, in the retest, I wanted to show that).
The Annihilator is designed to put a much larger hole than the head size suggests. The small surface area allows it to fly really well, but then displace a lot of tissue. And so, it makes a really nice hole.
Another cool thing about this head is that it’s a solid piece of 4140 tool steel. That is a really high quality of tool steel. So, it’s way more resistant to impact and much tougher than stainless steel, for example. It has a Rockwell hardness of 52, which is a pretty good balance of being soft enough to resharpen and hard enough to keep its edge.
You can just lay it flat on a flat stone or any kind of a flat edge surface and it is very easy to sharpen to a razor-like edge.
In my re-test, I used a half-inch layer of MDF surrounded by 1/3 of an inch of rubber foam mat. Beyond that was a gel block by Clear Ballistics, so you can see what happens to the broadhead once it enters the gel. (I will be doing this for all the broadheads I test this year).
Then, I shot it through a 22-gauge steel plate 5 times. (I like to shoot it through the steel plate until there begins to be significant damage to the blades. So, I basically see how many times it can be shot into the steel plate without facing significant damage. But, I stop at 5 because with some heads, I could keep going forever).
In terms of penetration through the MDF and gel, the Annihilator did very well. It did not do as well as some other broadheads I’ve tested, but it still had good penetration and made a nice hole in that MDF, as well as the gel.
Below, you can see the penetration of the Annihilator after going through the MDF and the rubber foam mats and into the gel. It penetrated 8-1/4 inches.
Below is a steel plate after I shot it 5 times with the same head. You can see the Annihilator really does make nice holes. Thus, it should displace a tremendous amount of tissue.
In terms of the durability of the edge (edge retention), the Annihilator is pristine. There is not a mark on it. It doesn’t quite shave hair, but it still bit into my fingernail… very impressive.
So, it’s durable as they come. It went through 5 layers of steel back-to-back-to-back with zero damage. That’s what that 4140 tool steel is going to do. It kept its edge really, really well.
The water drainage test was just other otherworldly. I don’t know any other word to describe it. It drained the bag in .40 seconds!
The reason I used the water bag drainage test instead of a water jug drainage test is that I felt that in a water jug, because the plastic is pretty stiff, sometimes the plastic folds in, sometimes it comes out, sometimes it stays in place. And so, the results are very inconsistent. Even with one head, I get different results.
But with water bag drainage test, and I fill it up 10 cups the same amount that the line is the same in all the tests that I do, try to shoot it in the same spot every time. It’s much more consistent and much more like an animal because the bag is a little more nimble, like the tissue or the hide of an animal. And so, what you see is kind of what you’re going to get in terms of the drainage.
The Annihilator goes into the bag and displaced so much water so readily, it actually created a back-pressure to the water. When I looked at it in super slow motion, I could it make the hole and suck the water right out of the bag. It was just amazing to see that. It’s an indication of what may happen with blood-letting and tissue damage within an animal as well. I can’t wait to test it on an animal at some point in the future.
Conclusion on The Annihilator Re-Test
I’m really grateful that I was encouraged to retest the Annihilator, because I knew it was a great head before. It tested really well in all categories except long distance.
However, now knowing after the re-test that it actually flies extremely well, even at long distances, it has gone from a very good head to a phenomenal head.
So, now I have confidence in this head at longer ranges. It gets a 10 out of 10 in terms of accuracy at long range.
The Annihilator did excellent in all of the test categories. This is a winner of a head and it’s something to really consider for pretty much any animal you are going after. Give the Annihilator a look. Great job, Annihilator!
And now a Battle! [Annihilator Original vs. Annihilator XL]
I was really excited to battle the Annihilator Original vs. the Annihilator XL. The XL is basically just a bigger version of the Original.
For my flight and some of the penetration testing, I used the Bishop FOC King Arrow from Bishop Archery. For some of the more harsh durability tests, like shooting through steel, I used the Bishop Frozen Fire Arms Dispatch (FAD) Eliminator. It has a nice footing on the end and that prevents the steel from cutting through the shaft.
And then for some of the concrete tests, I’m using a tank of an arrow by Bishop Archery. It’s called the GOAT (Greatest Of All Time). The Goat with a 125-grain tip weighs 1300 grains. Just the shaft is like a weapon in and of itself. It feels like a giant tent stake or even a spear. It is the best of the best when it comes to arrows.
So, let the Annihilator Broadhead battle begin!
Annihilator Original and XL compared
Here’s a good look at both models of the Annihilator heads below. The Original has a cutting diameter of 0.91 inches and the XL has a cutting diameter of 1-1/16 inches or 1.06 inches. So, 0.91, 1.06, about a 17% difference.
For my flight comparison, I shot two broadheads of each model as well as a field point, to compare.
Out of the box sharpness comparison
In the out-of-the box sharpness comparison, I used a sharpness testing machine, by Edge-On-Up. This tester holds a wire and measures how many grams of pressure it takes for the blade of a broadhead to break it.
Those all make triangular holes really similar to this. But, I do prefer those to just 3 slits. I mean they make a lot more internal damage and cause a lot more blood-letting than just the 3 slits do.
Cinder block test comparison
I shot both the Original and the XL into a cinder block to see how they would hold up. The XL showed out! See picture below.
How to sharpen the Annihilator broadheads
Now, you saw how durable they are and how they hold their edge really well. But, if you want to get them really sharp, one method of sharpening is super easy.
Because the Annihilator heads are 3-blade solids at a 60-degree bevel angle, you just one flat on any stone or any surface and just stroke it gently. Just be sure you have the same number of strokes on each side.
Do this until it comes out just like you got it from the factory. It’s super easy to do. You can even do it in the field. Again, you can do it on any surface. I love that about these 3-blade, 60-degree bevel heads.
You can also use the Stay Sharp Guide. They come out with individual sharpeners that are not very expensive at all for different styles of broadheads. And, in most cases, they put an edge on those heads better than how you got them from the factory.
They have a sharpener especially designed to put an extra sharp edge on these 3-blade, 60-degree heads. This is super helpful, because one of the drawbacks is that you can only get it so sharp with that 60-degree bevel.
What can I say about the durability of these Annihilator heads? They are absolutely fantastic!
Both of them performed really well and both had some great strengths.
My only critique of the Annihilator Original is the size of the cut. It has got some really cool features and it’s incredibly durable. It flies super well, penetrates exceedingly well, but I just have a little concern about that small cut.
And then you have the Annihilator XL. Even with it’s larger surface area, it still penetrated and flew very well and it was just still extremely durable.
So, for me and my hunting purposes, like hunting whitetails and hogs and stuff like that day in and day out, the broadhead battle winner of the Annihilator Broadhead battle is… the Annihilator XL! (check out the scorecards below).
I have to hand it to Innerloc Broadheads. The Carnage mechanical head definitely a cool and innovative-looking head.
I had been wanting to test these for awhile to see if the innovation translated to stellar performance.
So, let’s take a closer look at these heads.
As always, in this testing, I used my Bowtech SR6 set at 72 pounds, 27-inch draw, and a 460-grain Bishop FOC King Arrow.
Innerloc Carnage Broadheads Up Close
Now, the interesting thing about these heads is the way the blades stay together in the closed position. They don’t use an O-ring (i.e. the Afflictor Hybrids). They don’t use a retention clip. So, how do they keep the blades closed until deployment?
But, the biggest weakness is its durability. You saw what it did in the 1/2-inch of MDF when it lost a blade. I did the test again, just to be sure… this time it lost two blades. There’s just an inherent flaw in that pin that holds the blades together. It just seems to be breaking in some way.
So, I know a number of people have used these heads and hey, more power to you if you really like them.
But, I’ll tell you this, the Carnage is not going to make it in my quiver. But, check out the scores below and see what you think and see how it did in the areas that matter most to you.
