Trouble dispatching with captive bolt gun (graphic photos)

[averydeadbird]

I processed my first litter of rabbits today. For the first two, I used the Ballista penetrating bolt gun (https://www.bunnyrancher.com/store/p42/ ... _Gun_.html). I had watched the video on their website and read the PDF instructions on where to place the bolt, and to apply firm pressure. However with both of these rabbits, they didn't seem to die or even be properly stunned after the bolt hit them. Their kicks were completely different from what is shown on the video, and they continued with labored breathing. After I shot the first one, I hung it at my butchering station and slit its jugular to dispatch it. With the second one, I saw that it too wasn't killed or stunned, and I quickly shot it with the bolt gun a second time. Then I hung it and it screamed as I started to cut its jugular. I was appalled. I had expected easy, humane kills with the bolt gun.

I finished processing all the rabbits. (I used the broomstick method for the remaining four rabbits and had no problems. Their death kicks looked very similar to what is on the video, and after just a few seconds they went totally limp.) Then I pulled the head of the first one back out to examine it. I skinned it, then cut through the skull at the point where the bolt had entered. The hole looks like it's exactly where it should be, and the bolt definitely went straight through the rabbit's brain. Pictures attached.

What went wrong here??

Looks a bit high to me and possibly tipped enough to just barely slow death. I did always use my pellet rifle behind the ears angled toward the nose though so I haven't shot rabbits specifically from the front.

I was taught to whack them on the back of the head... (HARD!!) ... I was shown the Broomstick for the first time yesterday... I have to say ... I am a fan of the broomstick... easy, quick and sure.....

Broomstick works fine. I never trusted whacking them and then hoping to finish killing them with them fully unconscious. A pellet rifle was so easy though and with no distress for the rabbits. Less than the video of that website with the bolt gun because I didn't even restrain them. I set them in a pen on the grass and pushed the end of the rifle to the back of their heads. 99% of rabbits simply went still and kept their head calmly in place. A quick pop sound and they fall over dead with only 1 possible failure out of several 100. Thoroughly dead. Exploded brain rather than just a hole and only the hindlegs in spasms for a minute with no breathing, noise, or awareness. A bit gruesome as their eyes bulge out from pressure and the blood runs from their eyes, ears, and nose but very much instantly dead with no more handling than pulling them out of a cage and carrying each one to a separate open top pen. Really the only downsides were that you can't use the heads for anything due to a pellet being somewhere in them and the more difficult to contain blood than broomsticking.

I liked the idea of the captive bolt gun because it wouldn't leave a pellet or bullet behind. I feed the heads to my dogs. Broomstick worked great (better than I expected) in terms of quick death. However it was more difficult to maneuver the rabbit and stick into place. With the bolt gun, I could sit down with the rabbit between my thighs so that it was gently restrained and I could take my time to position the gun. Minimally stressful for the rabbits, since they had been handled and cradled from birth.

Have you looked into the Hopper Popper or a similar device? It's less fiddly than a plain broomstick, you just slide them in, give a sharp tug, and done. I've been using one for the past year and it's been very quick and easy for me.

 

[averydeadbird]

Yes, I'm planning on getting one of those if I can't improve my results with the captive bolt gun. What's funny is that I had ordered a rabbit wringer earlier, but instead of sending me 1 wringer and 1 butchering station, they sent me 3 butchering stations. Since I was planning on having friends over to help with butchering day and in the meantime I'd also purchased the bolt gun, I just kept them. Now I'll need to place another order. :lol:

 

[akane]

The existence of a pellet did cause some waste since most of mine went to the dogs. I have a rabbit wringer but never really somewhere to install it permanently. I was looking into a captive bolt gun at one point. I couldn't really find much several years ago besides something like the $500 zinger. Not worth it just to avoid the pellet from a $40 rifle that did the job or a free "broomstick".

I have always used cervical dislocation, except with older bucks, with them- I used a pellet gun, or a piece of 1/2 inch water pipe to whack them on the head....

I had the same difficulty with my bolt gun. I was so excited by the more humane way of killing, or so I thought. I was using the broomstick. I am very happy with that method, other than the pooling of blood at the shoulder (even though I cut head off super quick and bleed out fast). That and being very pregnant not able to bend much, I bought the bolt gun. I placed exactly like directed and perfect kill on a sr buck. I was encouraged. I tried to do several other rabbits of various ages. Many of them were still alive after. Laboured breathing, kicking like crazy (not the normal after death kicks). Obviously alive. I am pretty tough, but found it hard to watch. Second time with bolt gun still didn't kill them and resulted in a bloody gun. I finished their suffering with the broom stick. I was almost traumatized and of course that was not humane for the rabbit. I am almost embarrassed to tell it but for educational purpose, I share my story. I did think that it was just user error on my part (even though I followed instructions), and I thought that I must just have to try again and learn how to do it, adjusting slightly. So I placed the gun slightly closer to the ears than I had it the other times. Instant kill, just like the first. That's better. The first rabbit was an angora, so I didn't aim as well with all the fluff, and that explains why by chance I got it right the first time. So now I will try again when I have more to process and I will place it slightly higher than I was on the failed attempts. After a bit if it's still proving too difficult to get near instant death EVERY time, I will go back to the broomstick. I really want this to work though, as it's the most ideal way to dispatch if it works every time.

 

[averydeadbird]

Jessykah, thank you SO much for sharing your experience! Very similar to what I just went through. I really want to figure out why it didn't work as well as expected, but I don't want to keep experimenting on the poor rabbits if I don't have any idea how to fix it.

My mama doe is already pregnant with her next litter and they will be due for dispatching around early March. If your next attempts are before then, please let me know how it goes!

I think the issue of a bolt not producing the same force as even a pellet makes not just placement but angle more important. People have even recovered to live normal lives or close to it after impressive injuries from their brain being impaled and reports of people or animals with smaller brain area to damage surviving nail guns is not hard to find. When we are talking about destroying the brain not just enough to kill but to kill instantly the damage has to be surprisingly specific. Unfortunately precision is hard without practice and most don't have an experienced person to show them.

It sounds bad but it's actually become kind of instinctive for me to determine where to aim something like a bullet or how to cervical dislocate by hand after having raised a few different small food animals and a lot of types of rodent feeder animals. Even using a different but similar method you start to figure out what works cleanly to apply it another way. It comes back to doing it enough times though and that is not a common thing these days. I had a heck of a time finding someone to help me with those first quail I ever butchered and my method of lopping heads with shears proved more effective for me. Less for them as they kept failing to get as sufficient of cut even after swapping pairs of shears. It wasn't what they were used to but after that first batch of 200 quail I could cleanly dispatch any poultry including guinea fowl and with an axe. Same concept but far cry from starting out lopping quail heads off over the sink by feel because I couldn't do it without covering their heads with a towel. My first axe cut failed too as I adjusted for aiming from a distance at the same spot as holding shears around quail.

I could probably still recall every failure of every method with every animal nearly 10 years and possibly pushing 1000 individuals later but it means I hardly worry about not being able to cleanly kill something when I have to and after a couple years of not raising my own food or feeders I have a need to again. If I don't get more rabbits and rodents I'm going to have to give up a few carnivorous animal hobbies. Frozen whole prey gets expensive and my husband is still going on about arctic foxes. :roll: The times I had to experiment a little are probably worth it for the future animals given the variety of animals and uses we have for them between both enjoying the idea of raising human food and exotic carnivores or omnivores. Doing only rabbits with a single use it might be better for some to stick to whatever works without fail from the first time. It depends how much need you have for such knowledge.

Well, I don't know commercial captive bolt guns, I built my own, featuring a 6mm diameter/30mm long bolt, and force beyond good or evil (need to step on the handle and pull with both hands to **** it). For me, besides bopping them with a flat steel bar, this is the best method, after firing I quickly rotate the bolt so that even if I didn't hit the sweet spot right away the brain is destroyed thoroughly. I always have my army knive or that steel bar close as a backup method.

I only had one real failure over the last 3 years, rabbit ****** just the moment when I pulled the trigger and the bolt entered too far on one side, well, it's really good to have a fast backup.

I don't try broomsticking, that involves too much handling them and my physical strengh isn't exactly even close to average.

 

[ladysown]

so good to read these stories.

Just remembered to post this update! I emailed the Bunny Rancher people and got this reply to my pictures:
"I think the placement was not far enough back, and it's off center. It should be back between 1/8"-1/4" more, and with the bolt pointing through the cranium towards the occipital bun or supraniac fossa. The "X" envisioned on the head should use the back corner of the eyes as the distal ends and the back of the ears as the proximal ones."

With that extra guidance, I feel much more comfortable trying the bolt gun again with the next litter.

I watched the "Bunny Rancher" videos again and I noticed that (on both captive bolt models) the penetrating bolt stays extended after the firing. This can be significant, because the extended bolt can also be used to cause additional damage.

Just remember that the brain is very soft tissue and it can easily be destroyed. The force of any captive bolt is required to brake through the hard skull, but once penetrated, the brain inside is completely defenseless. There are not even any pain receptors inside it.

When I dispatched my guinea pigs, I would hold the skull and swishes it side-to-side then up-and-down raking through the soft tissue of the brain. I know this sounds gruesome, but it is a way to speed the death along for the poor creature that will be my lunch. This way, once the guinea pig's skull is penetrated, it will have no further experiences of anything.

I know the bolt gun is $60 and you don't want to bend the tip. You might need to take care not to use it like a pry-bar against bone fragments. But, if you just probe around inside the soft tissue, it should not damage the device. In one video produced by "Bunny Rancher", it did look to me that, the operator did sweep around a bit, while extracting the bolt from the rabbit's skull.

 

[averydeadbird]

Thanks for your reply, Ghost. I actually forgot to give an update that a couple of weeks ago, I had an opportunity to use my bolt gun again, on an adult male rabbit. I double-checked my placement and made sure to point the bolt toward the occipital bun/supraniac fossa. This time it worked perfectly!! Instant death. I think the angle of the bolt was probably the problem on my first two tries - I had been holding it too vertically.

I remember reading about people using bent wires to swish around and destroy the brain in larger animals, after using a bolt gun. It does sound a bit gruesome... but considering that I already skinned the face off a rabbit, cut open its skull, and poked at its brain, I guess it's not really a big deal. I will keep that in mind for the future.

Having used many MANY dispatch methods I started using long-handled branch loppers for everything small enough to get the jaws around the neck.

It works fantastic for rabbits, duck, geese, turkeys, chickens, guinea pigs. I bet the bigger sizes would even work for goats.

The rabbit can stand on the table while I put the jaws round its neck, right behind the head and when I gently press down so the tips are on the table the rabbit just stands there. Then I close the handles which bring the jaws together and instant death. With no way to mess up or strength needed.

There is usually a bit of blood from right behind the head where the skin is the thinnest but the rest of the skin is so tough that only the bones cut through, the skin just moves through the lopper jaws.

I did design a bolt gun once years ago - found it again when sorting papers - but had no money to take it to the trial stage. Tossed it back in the box, one day, one day. :lol:

 

[averydeadbird]

GBov, do you use loppers that have straight blades? I tried cutting off a chicken head with loppers that were curved (like this: https://smile.amazon.com/Fiskars-28-Inc ... 000BX1IB6/) and the curve pushed the neck away from the hinge, so I couldn't get the head off in one cut. I switched to hedge shears (like this: https://smile.amazon.com/Corona-HS-3244 ... 007GYOYJG/) and they work well, but I have to press hard with both hands - less leverage with the shorter handles.

Yep, just like that. I place the jaws round the neck and then press the tips of the jaws against the tabletop when doing rabbits (or tree trunk when doing turkeys outside) so no chance of the jaws slipping off or the animal twisting out.

The heads never come off as skin is both tough and flexible enough to just slip through the jaws but the neck bones are clean cut through so I can´t miss my kill.

Just like all of us, it is only the botched kills that remain in my mind, not the THOUSANDS of times I have gotten it right! :roll:
