The Valkyrie heads are machined out of a single chunk of S7 tool steel. that is brought to a Rockwell hardness of 58 to 60 which is really hard.
Now, it’s important that you don’t compare that to 58 to 60 in a stainless steel, because with an S7 tool steel like this, the impact resistance is many times greater than that of stainless steel.
So, you are getting the benefit of a really hard edge and really hard blade combined with really tough impact resistance as well.
The Valkyrie is a 3-blade design. The cutting diameter is relatively low at 1 inch. But, with 3 blades, you are getting an inch-and-a-half of total cut which is a lot more than most 2-blade heads.
The overall purpose of the Valkyrie design is to maximize penetration. And that’s why this “swept” design in the short Jag head, and in the regular-sized Jagger.
The blades of the Valkyrie heads are also completely coated with a Cerakote ceramic finish. This aids in resistance to the elements, which a tool steel typically does not have. It also provides a less of a glare and it aids in penetration, to give it a bit more smoothness through bone, tissue and hide.
For this test, I’m used my Bowtech SR6 set at 72 pounds and I’m using the whole Valkyrie system pictured below. It comes with VAP arrows 0.166 diameter and with their titanium centerpin and the broadhead. The arrows even have their own fletching.
I was very eager to test these heads. They looked like they would penetrate well. They also spun very true and looked and felt very sharp. I also wanted to test for long-range flight, edge retention, penetration and durability. So let’s get to the results…
To test the sharpness of the Valkyrie Jagger, I examined its ability to cut paper not only out of the box, but also after up to five strokes of the arrow shaft against the blade edge.
And, I will note too that it’s fairly easy to sharpen. When I’m sharpening it, I use a paper wheel. You can use whatever you want or you can just mail it back in. They actually sharpen them or will even repair them if they need repair… all for free. ($10 shipping and handling to send the head in).
Epizootic Hemorrhagic Disease (EHD) and Chronic Wasting Disease (CWD) are the two biggest diseases that can impact your deer herd, but more specifically, your mature bucks.
If you have never heard of either one, let me give you a quick summary.
EHD | The Specifics
EHD is in the same group of viruses as Bluetongue (BT) Virus and because clinical symptoms are similar between the two, they are generally clumped together and called Hemorrhagic Disease.
These types of viruses are transmitted by a biting midge, usually in late Summer or early Fall but can also occur in the Springtime.
Clinical symptoms are highly variable. Initial symptoms include a feverish state where some animals can lose their fear of humans. There was a video of a buck that went viral because it stumbled through a burning campfire on its way to drowning itself in a river, all while people stood around wondering what the heck was going on.
Deer with EHD may die within 1-3 days after getting bitten if they have no immunity to the strain of virus that has infected them.
As deer attempt to relieve their fever, they often become dehydrated and will be found near water.
Once a hard frost hits the landscape, the threat of further EHD outbreaks is complete for that growing season, but as soon as midges come back in the spring there is a chance for further outbreaks.
CWD | The Specifics
Chronic Wasting Disease (CWD), on the other hand, is caused by a protein that changes its shape to a non-functional version. This prion protein normally resides all over the body, but is concentrated in the lymphatic system, brain and spinal tissues.
Infected deer show no clinical symptoms for up to 18 months but are capable of spreading prions even before they show any outward sign of illness.
In the later stages of the disease, animals lose coordination and become lame. They also lose their appetite and fear of humans. They are typically found with dropping ears and head in a lower position.
CWD has gotten a lot of press lately because of the concern to potentially impact humans, whereas EHD poses no direct threat to humans.
Notice how I said ‘potentially’ impact? That’s because there’s currently no evidence that it will impact humans, but that doesn’t mean it will always be that way.
CWD is in a group of diseases known as Transmissible Spongiform Encephalopathies and in that same group of diseases is one that infects humans, called Creutzfeldt Jakob Disease (CJD).
A variant Creutzfeldt Jakob disease (vCJD) can be acquired by eating meat from cattle infected with a similar disease called Bovine Spongiform Encephalopathy (BSE), also known as Mad Cow Disease.
The fear is that one day humans will someday be susceptible to CWD, even though that day has yet to come. That’s because all animals carry some type of prion protein, but a major difference is that the human prion protein has slightly different amino acid structure than deer.
There has also been recent concern that CWD can be transmitted to macaque monkeys, which are genetically much more similar to humans, but that information has yet to be published in scientific literature.
What causes the normal prion protein to change into the mis-shaped disease state remains uncertain, although there are many theories about how this could happen.
EHD Compared to CWD
The take home point is that both EHD and CWD can impact deer, but EHD is less of a long-term concern with your deer herd, because the more a deer herd is exposed, the more immunity it can build up.
CWD, on the other hand, progressively gets worse until mature bucks are almost impossible to grow on the landscape because they become infected and die before they can reach the older age classes.
This phenomenon is rare because CWD prevalence is low across most of the range of white-tailed deer, but can occur in certain areas where the prevalence is above 50%. That means the chance of a buck having CWD would be the same as flipping a coin to heads, and if you see a buck older than 3 years old in that area, they are more and more likely to contract it and die before reaching 6 years old.
This is because mature bucks move about the landscape more often than females, especially during the breeding season.
Bucks also mutually groom each other in bachelor groups during the summer months, so they have more opportunity to spread the disease than female groups, which tend to keep a more consistent home range throughout their lifetime.
Here is a table to explain the differences between EHD and CWD:
Mis-shaped prion protein
Mortality when contracted:
Duration of clinical illness:
24 hrs to several weeks
18-24 months, followed by death
Long-term herd effect:
Build up Immunity, herd rebounds
Unknown, but might lower herd productivity if prevalence gets too high. Mature males harder to grow.
If you have a pond edge, plant vegetation that can withstand moist soil right up the edge of the water.
Spread quick growing seeds like rye grain on areas of a creek bottom that have been exposed to flooding and try to reduce the amount of mud exposed.
Fogging for insects around ponds on a still morning may also reduce adult populations thus limiting the spread of disease.
You can also keep your herd healthy by supplemental feeding and using minerals. Ani-Logics Outdoors has produced a health additive for their feed and minerals that can increase immune system function. When the immune system is firing on all cylinders, the deer that gets bitten by an infected midge has an increased chance of survival. Those that are in poor bodily condition when bitten by the midge have a much higher chance of dying.
How To Limit CWD
As for CWD, the best thing you can do to prevent the spread is not to move the carcass of deer harvested in a CWD area. Also, dispose of the remains in a state approved landfill or incinerator.
If you harvest a trophy buck in a CWD area, make sure the taxidermist you use is local, and make sure they properly dispose of the brain and spinal cord tissue without putting it back on the landscape.
If everyone hunting in a CWD area removed all the CWD positive carcasses off the landscape, prevalence would remain low enough that no population level concerns would ever occur. There would be no way to eliminate the amount of prion proteins already deposited on the landscape, but at least we wouldn’t be adding more fuel to the CWD fire by always putting more diseased prions in the woods.
If you hunt in an area that is not known to have CWD, you should still get your deer tested because deer have been known to make very long excursions outside of their normal range.
Here in Minnesota, the DNR recently tracked a collared deer that made a 75-mile one-way trek. Thankfully it was not CWD positive at the time, but if one deer did it, that means other can as well.
Best of luck in having a healthy deer herd!

But before you buy a riflescope, learn why you should even buy a riflescope in the first place.
Some are built for tactical purposes while other sniper/hunting scopes specialize in longer-range targets. A quick pro-tip here is that it’s generally better to have too much scope than not enough. So, if you must err on the side of caution, err in favor of the scope.
I Have A Riflescope… Now What?
Okay, so you’re happy with the scope you’ve purchased, and now you want to get out and shoot, right?
Only after you have properly mounted your riflescope can you sight it. This component is just as important as anything else because it is how you customize the rifle to your own anatomy and mechanics.
Your arm length, eye spacing, and the unique way you hold the rifle are slightly different from everybody else, and these subtle differences can make a big difference downrange.
You might find it is easiest to sight your rifle at a local shooting range. However, if you live far from one but have a lot of land nearby, just make sure you’re shooting in a safe direction where there is no chance of passing hikers, campers, etc.
The first thing you need to do is make sure your reticle is in focus.
The reticle is the shape (crosshairs, a singular dot or circle, a triangle, etc.) you see when you look through the scope, and its function is to indicate scale or location of an object.
Look through the scope to ensure the whole picture is sharp. If it’s blurry, twist the diopter adjustment on the scope, which is typically going to be the end of the scope closest to your eye.
Something to keep in mind is that when shooting is that you will be focusing your naked eyes way downrange, scanning for targets or game, and then you’ll quickly switch to the scope right in your face.
Your eyes take a little time to adjust, so the view through the scope can be a little blurry for a few seconds.
To eliminate this lag, look away from the scope and let your eyes focus on something else at a distance. Stare at it for a few moments, then quickly look through the scope and in the brief moments before your eyes adjust, determine if the picture appears blurry. Keep doing this until the image is sharp and in focus immediately upon looking through the scope.
Step 2: Boresighting
Boresighting your rifle first will save a lot of time and ammo.
This will take just a few minutes and will ready your weapon for the fine-tuning we are about to do.
First, securely mount the rifle to aim downrange at a highly visible target 25 yards away. Then, remove the bolt so you can see straight down the barrel at the target.
Look through and aim the barrel center mass. Next, look through the scope to ensure the reticle also lands center mass. You will likely need to adjust the scope’s turrets to achieve this. The turret on top adjusts the scope’s elevation (up and down) and the one on the side adjusts its windage (to the left and right).
Once your reticle is adjusted center mass, replace the bolt and get ready to start shooting.
Pro-tip: There are even specialized zero targets you can use that are gridded to help precisely determine the adjustments you need to make. You’ll see why that might be useful later.
Sighting requires great precision, so make sure the rifle is either mounted or thoroughly supported for this step.
Replace the bolt, insert your high-quality ear protection, and fire three rounds directly at the bullseye of your target at 25 yards. You will probably not hit the bullseye, so focus more at the consistency of the shot group.
If your three shots are really close to each other, but the whole group is about 1 inch south and 2 inches west of the bullseye, you need to adjust the elevation for 1 inch and the windage for 2. It looks complicated, but it’s really simple. The turrets we were playing with earlier in the article are what we will now use to fine-tune your scope.
But before I go in-depth, here’s a quick primer on elevation and windage adjustments:
Usually one click changes the location of the bullet’s impact by ¼ inch at a target 100 yards away. The way we represent that is “1/4 MOA,” where MOA stands for Minute Of Angle. Four clicks will move the bullethole one inch in the direction indicated.
But, if the target is only 25 yards away, we need to move the dial 4x as many clicks to move the bullethole the same 1 inch. If the target is 200 yards away, conversely, 2 clicks move it 1 inch. Four hundred yards away, 1 click for 1 inch.
So for the example above, we need to rotate the turret 16 times to elevate 1 inch and another 32 clicks to the right. The turret itself will indicate which direction to turn and the MOA (although most are ¼).
Once your scope is sighted for the target at 25 yards, it is time to extend the range to 100.
Fire another three rounds for your shot group, then determine how far off the bullseye the group is located.
Measure the deviation and adjust your elevation and windage in the same way we just did, bearing in mind that 4 clicks at this distance will equal 1 inch.
Fire another shot group at your 100-yard target, and if they hit where you wanted them to, you have successfully sighted your scope.
