Big Bore Airgun Hunting: Do Deer Have an Off Button?

We all dream of taking a shot at a Deer with our big bore airgun and having its legs buckle and anchor in place. We crave the visualization of watching the immediacy and drama unfold through our scopes for that immediate rush of heart pounding success. It is even better if it can be recorded and share it with all you air heads later on!

So can the Deer "off button" switch get flipped when you take the shot - yes. Does it always happen - NO FRICKEN WAY!

If some mighty hunter in the online hunting group you are part of says they "always drop their Deer dead right there (DRT)" THEY ARE LYING!

So if DRT shots don't always happen, then what type of shot is statistically the best to take? Head shot? NOPE! Not shooting subsonic relatively loopy trajectory big bore airguns anyway.

Deer have crazy good reflexes and I don't care if you are a Rick Rehm special ops sniper wannabe - DO NOT take that head shot. One inch off with the Deer flinching the slightest and you are in the sinus cavity vs. the brain or spine. You now have a wounded Deer and not a pretty ending.

Over the past few years of obsessing and big bore airgun Deer hunting like crazy I think I have it figured out. The key is achieving a good blood trail which in my opinion is more important than anything. So how do you ensure a good blood trail?

Your goal for the best blood trails is a full pass through with clean entry and exit wounds - Double Lung - PERIOD!

Pop Quiz: How many holes will you get blood from when you double lung a Deer with a full pass through? Is the answer two? NOPE! The answer is three!

Here is the entry wound:

...and here is the exit wound:

When you double lung shot a Deer you get blood trails from both the entry and exit wounds and the passthrough relieves the pressure of the chest cavity making the blood flow better.

The third hole I speak of is through the mouth. When the Deer is double lunged it will expel blood through the respiratory system through the mouth as it exhales when it is running and is often the spray on the ground you see towards the end before it goes down.

In my opinion, this double lung shot is the most ethical shot with the highest statistical probability of a clean harvest with as little tracking as possible with a big bore airgun.

In the shots you see here from my Tactacam FTS scope kit I attempted a few higher shoulder / double lung shots and the results were awesome. Both Deer went down within 30 yards and great blood trails with the NSA 290 grain HPs. Still no "off button" though.

Using the Nick Nielsen NSA 290 grain HP slugs paired with the AirForce Airguns NEW .45 Texan with Carbon Fiber Bottle from Airgun Depot is hands down the best Deer hunting combination on the market right now.

I see airgunner newbies asking questions here on AirgunNation.com about which big bore airgun to get and I would like to provide my journey as a big bore airgunner as an example.

Just go big right away and go with the Texan .45 with the new carbon fiber 3625 PSI bottle. I am not just saying this because I am a Fan Boy of Airforce Airguns (which I am), but I am telling you this because it is true.

I know there are big bore airgun options out there in the $550-$750 range, but trust me you want that double pass through and a 200-300 FPE big bore airgun is marginal. When you get into that 75-100 yard range it starts getting questionable if you will get through both sides of the Deer.

After owning those 200-300 FPE guns for awhile you will most likely be looking to Chad Simon from Lethal Air with his African Air Ordnance upgrade kits (which are a great option), but why not just do it right the first time a get a Texan .45 with Carbon Fiber bottle with 700+ FPE capabilities?

Hit a bone or shoulder with those less powerful guns and statistically speaking, you are going to have a single entry wound. Will the Deer still go down - yes eventually. But when I am in the woods and after obsessing and planning all year long, I want to take that X factor of passthrough out of the equation.

Even with the Texan .45 CF Series - if you have a quartering shot, you still might not get the full pass through. I was lucky to have hit the liver upon entry on this one and got immediate blood trail. The slug still broke through the back shoulder and embedded into the rear hide. Watch here: https://youtu.be/gf3S5_T8MFw

The lower powered .357 big bore airgun options on the market are good guns and yes - they have taken Deer. As a matter of fact, I started this journey with a .357 Texan and shot 3 Deer in the first year, but had some issues. The first two went down within 75 yards, but with little to no blood trail.

The 3rd Deer that year was a 6 point buck shot at 75 yards and was perfect heart / lung shot placement with mule kick reaction. We didn't recover till the next spring. Zero blood trail during a cold November rain storm and he slid down a steep ravine into thick cover after about 150 yards. My uncle found him the next spring while Morel mushroom hunting. So we have the antlers on the wall and the story to tell.

I have had a lot of success in recent years with this Texan series of big bores, but not like this year! I haven't had a single Deer go more than 40-ish yards and have had two drop within 25 yards. With that said, I haven't found the "off" button where they drop right in their tracks. I think the key to that "off button" is hitting a nerve bundle somewhere within the system.

So this year was hands down my most successful year so far for Deer hunting and it isn't fully over yet. Here in Michigan we still have Dec. 23, 2019 – Jan. 1, 2020 for the late antlerless season and I have 2 more tags to fill.

So I hope you can use some of this info to help your decisions with both purchasing of a big bore airgun and your shot placement on Deer.

In 2019 we had more states than ever before with legalized big bore Deer hunting (thanks to the AIRGUN SPORTING ASSOCIATION) so we are getting more intel from the field.

Please share your stories even if it ended in an unrecovered Deer. We learn more from our failures than our successes and sharing as a community will make us all better big bore airgun hunters!
 
Personally have taken deer that were DRT in those instances where you see there ASS, yet back of the head visible. A shot placed at base of skull / neck area from the rear is an INSTANT lights out and total body disconnect. Literally a sack of spuds drop !!

That is a pretty small target!

The heart/lung shot is the high percentage shot everytime in my book.
 
Heart Lung agree ... just at times you have nice buck that simply is giving you a kiss my ass walking away. Small click or odd sound they stop and look giving you a semi broadside head / neck profile that is an easy 4-6" area to hit. Even a low shot takes out there throat and jugular, high no more spine ... middle of either you generally get both !
 
I seen a video on here or youtube? a fellow shot a deer with a .25 cal impact I believe, it wasn't a large deer and he shot it from the deer's right side behind the shoulder from what was a stated distance about 60 meters. He stalked it from behind some brush/cover. There were 2 other deer with the one he shot. The amazing thing to me was none of them took off. The deer he shot jumped like it had been stung by a bee then wobbled around like it was drunk and dropped. The other two just looked around confused. I guess they didnt hear the shot. Later in the video he was carving it up and showed what appeared to be a heart shot.


 
I definitely agree with the double lung shot being the best choice. An animal’s head is the one thing that is almost always moving. Even if you make a sound and the animal freezes it’s now highly alert and ready to bolt. I had a bad hit on a raccoon that moved just as I shot. I still use the sound method to get a headshot on raccoons, but I make sure to shoot quickly. Great post, good information for hunting big game with an air rifle. 
 
I've shot plenty of deer in my time but none with an airgun. I would think it would be similar to shooting them with a round ball out of a muzzle loader. They always ran a bit when shot with the round ball but also left good blood trails. Now I use a .35 Rem and all the deer that I shot with it folded on the spot and never took a step. I also use .357 and .44 leverguns and they run a bit but also leave a good blood trail. Only once did I shoot a deer in the head and it dropped right there however I will stick to my chest shots.
 
EGO vs. ETHICS? Longed winded comment (as usual) but here we go.....

I love it when I make posts like this because it draws out the ego of hunters and the hunter "ethics police" in such a huge way! The problem with these discussions is ego and terms like "ethics" start flying around and really muddies up the conversation. Getting as involved as I have in big bore airgun hunting in recent years has made me take a pause and change the vocabulary I use so people don't take things so personally if we were to say something is an "unethical" shot. 

Let me say it this way instead. A head shot on a Deer is statistically STUPID. We all can agree that a missed head shot with an airgun most likely isn't going to end well. With all my AGD Long Ranger stuff and the Guinness World Record insane amount of ballistics homework I have done in the last few years - there is a harsh reality we all must face as big bore airgun hunters. Even with the new Texan .45, this isn't high velocity / supersonic ballistic trajectories we are dealing with here! Your slug is dropping anywhere from 6 inches to a foot at 100 yards depending on what gun and ammo you are shooting.

To put that into perspective that is equivalent to taking a head shot on a Deer at 200-250 yards with a .308. I don't know a single hunter Dad in this world that wouldn't whooop the butt of his son or daughter who attempted that shot. I know my hunter privileges in my house would be gone right away growing up. So why do we see so many grown men bragging that a head shot is their shot of choice with an airgun?

So backing away from the "ethical" argument, let's play a little game or shooting statistics and probability to take the emotion and ego out of this. 

1575653228_9957607835dea8f6c365974.33217345_baloon.png

There is a roll of $100 bills wadded up into two balloons and placed out at an unknown range but within 100 yards but over 50 yards. One balloon is blown up to a 10 inch balloon (the size of Deer lungs) and the other one is blown up to only 3 inches (the size of a Deer brain). You are spun around and then given the "go" to acquire your target and take the shot within 5 seconds and not knowing that exact range to the balloon. Statistically speaking why would you take the shot at the 3 inch balloon? That is just statistically STUPID! The probability of you hitting the 10 inch balloon is SOOO much greater and a double lung Deer will die 100% of the time. 

Furthermore, these are not firearms slinging thousands of pounds of energy that often "hide" or make up for a bad shot placement. Before airguns, I grew up hunting with 12 gauge shotguns as that was the legal weapon of choice in southern Michigan. I had an old timer once tell me that the force of the impact from a 12 gauge shotgun on a deer often just shocks the hell out of them and they just keel over. Not sure if there is any truth to this, but a high shoulder shot with a 12 gauge basically makes their body tense up so quickly and abruptly that it snaps their spine. Not sure how much of that I believe, but with a 12 gauge shotguns, that is over 3000 FOOT POUNDS OF ENERGY from a 1 oz slug. 

So with big bore airguns we are talking at best 700-900 FPE at the VERY most with a hot rodded AirForce Texan, but TONS of people using 200-300 FPE big bore airguns. So the force of energy we are talking about here is more in archery land. If you have been an archery hunter as long (or longer) than I have (30 years) you know damn well Deer will run like crazy even after a good hit into the vitals. They very rarely DRT (Die Right There).

So here is the hard truth about big bore airguns. As compared to a firearm they a NO WHERE close to the "shock" power and as compared to archery they have NO WHERE near the cutting characteristics of a broadhead. So the tough fact we all need to accept is you are basically Deer hunting that amounts to about the force and cutting radius of a field point arrow (ok a tad bigger - but not by much). So if you have two big 10 inch balloons sitting out there - just pop them and take home your meat. Save the hero shot for the next Long Ranger Challenge or sign up for Pyramyd Cup or EBR or RMAC. Just sayin.
