The OTHER side of an accurate shot II

11/20/2013

12 Comments

 
Last week we discussed the anatomy of the rat. 
As one of the pre-eminent airgun preys, the need to place the rodent in first place was indisputable.

This week, as promised, we will look into the anatomy of the pigeon.

Yes, the common, bell-fry pigeon (Columba Livia & C L Domestica), ubiquitous in almost any place that has high structures, constructions, or buildings. Especially if those high constructions and buildings have hollow spots, and there is food available nearby.

To say that pigeons are a pest in some environments is an understatement.
Cities that for centuries had regarded the pigeons in their plazas as tourist attractions have now declared them "persona non grata" (undesireable persons), and those cities have imposed fines, heavy fines, to those that feed them.
Farms, silos, grain storage and transfer facilities do battle with them.
Churches and barns; houses with high lookout points; under highway bridges; even some electrical utility lines crossings where there are several posts/towers and some transformers provide a place for these critters to nest.

Some shooters called them "winged rats". And, depending on the location, they can even be quite toxic just to handle. City pigeons are usually saddled with genetic malformations, diseases, parasites and a host of other nasty riders. So, HANDLE WITH CARE!

Country pigeons are normally much healthier and some of them are even edible. ANALYZE them and make sure you are taking all necessary precautions. IF you decide to cook them, cook them well. Nothing "rare" about game meats in general, but in the pigeon's case the warning is even more important.

And yes, we will be taking about hunting, if you are bothered by the activity, STOP READING!
Having issued the standard disclaimer, let's get down to business:

Pigeons evolved from ancient cliff-dwelling birds. They have become dependent on the human race for most of their sustenance and population growth.
They are STRONG birds, their breast meat is RED, dark red, showing that the muscles are used and used heavily.
The feathers are hard and strong, they provide the bird with the necessary stability, manoeuvering capability in the air and loft, and they shield the bird from pretty low temperatures in winter. There are TWO layers of feathers: the ones we see which are the ones the bird uses to fly; and the under coat, that is soft and insulating.

Usually, shooters think that the best place to hit a bird when it's facing dead front to the shooter is the lower chest. Hmmmm . . ..  Not so much. The birds have an organ, called the "Crop" that is filled with food. usually grains and associated sand.

The crop is, then, like a sand bag.. ¿Have you tried shooting through a sand-bag?
Well, now you see why it is not such a good idea, unless you shoot a high power rig.

From the bottom/rear, birds have a "gizzard", since birds have no teeth, they use small stones and grains of sand to grind the grains they eat. The gizzard is very muscular and the sand/stones it contains makes it even more of a sand-bag than the crop.

From the sides, the birds have a TRIPLE layer of very hard feathers because the wings get folded in two and then you have the outer layer of the body. That makes three layers of tough feathers to shoot through.

The head / neck area is always there but, ¿how much of that area is animal and how much is hollow feather fill?

OK; let's look at some anatomical diagrams and let's try to come up with conclusions:
Picture
Number 16 is the "crop", the dotted oval numberd #14 is the position of the heart. From a fully frontal position, the pellet would have to go through the crop to reach the heart. From the rear/bottom, the pellet would have to go through the gizzard to reach the heart.
Now look at a complete pigeon in the same position:
Picture
The heart really lies where the #26 is pointing to. Much lower than most shooters aim at.
Aiming higher only places the pellet right at the wing folds. So not only does the pellet has to traverse three layers of feathers, but also bone and bone joints.

Lastly, we do need to consider that a shot to the lungs area (#3 in the internal diagram) while useful and final, will allow the birds to take off and fly for between 25 and 100 yards. Which can make the dead bird land where it is irretrievable or bothersome.

The broadside head/brain shot is a hard shot because the brain and the medula oblongata lie really at the REAR of the eye, and the target is, frankly, very small. A shot to the eye usually has the effect that the bone fragments created by the pellet impact will cut all nervous system activity, so while in reality we are not shooting directly at the brain, we are relying on the effect of the impact to destroy the main organ.

With a VERY stable position and a VERY accurate rig, the rear brain pan shot is a good shot, but things seldom come presented in the ideal way.

There is a shot that is sometimes misunderstood: the shot from the back, either on the level or from slightly above..

Sometimes, though not often, we can shoot at pigeons on the level or even from above. Usually when we have established an elevated blind of some sort. In this case the heart becomes an open target.
We cannot stop from marveling at how nature disposed things, through evolution, to be in such a way as to protect the heart and lungs from most attacks at ground level, or from below, but there is little protection from above. And we cannot stop from marveling at how hawks and other birds of prey have realized this and aim their talons at exactly the spot we will describe:
Think of an imaginary line that cuts the pigeon in two horizontally, and then another line that bisects the pigeon vertically. Where these lines cross when the pigeon is viewed from the rear or, even better, a little above, the pellet can find the lungs and the heart with ease. Look at the frontal/dorsal diagram:
Picture
#33 points roughly to the heart, the dotted outlines to the left and right are the lungs.

I know there are quite a few very successful hunters out there that routinely use 0.20" to 0.30" cal airguns to hunt pigeons, at energies of between 20 and 50 ft-lbs; I've done it myself with D54's, Talons, and Steyrs. And this is all good and is well. BUT by going ONLY to those power levels sometimes we are missing on the "indoor" Pigeon hunts, where large amounts of pigeons in a stable, barn, warehouse, or any other large building, becomes completely off-limits to them because no owner, and no facility manager, would like to see his building's roof poked with pellet holes.

In these cases, my favourite tool is a 0.25" cal rebarrelled Crosman 2200 that is quite accurate with H&N Pointed Pellets with 7 to 10 pumps:
Picture
It took some tuning to make the SpitzKugeln to fly accurately, but it was done. At 10 ft-lbs they dispatch a pigeon with little noise and very reliably out to 20 yards. For longer shots, out to 35 yards, I can put out 16 ft-lbs with the max. 10 pumps. The Spitzkugeln is a 25 cal. 25 grain pellet, so it is somewhat "light for caliber", but the penetration afforded by the point, even in the realm of medium to low power makes them a good projectile.

Also, the challenge of shooting almost straight up into the roof girders is something that also needs some learning.

And finally, most pigeon shooters do enjoy a little bit of bragging and cooking, we each have our own "secret rub" for game meats, and I am no exception, but mine is, truly, secret. So don't ask! LOL!

Enjoy!
Picture
Picture
ALWAYS make sure you know you have a GOOD backstop.
ALWAYS make sure you know where the pellet will end.

Be a SAFE hunter

Good shooting!

Estimado Héctor.

Por aquí en Perú se está haciendo muy común preparar a las cuculís que cazamos (Zenaida Asiatica) en forma de anticucho, utilizando la pechuga. Una delicia!.

Saludos y éxitos en tu Blog.

About your Crosman 2200/.25

An Old Indian Trick (http://www.network54.com/Forum/79537/thread/1134532244/An+Old+Indian+Trick+%28work+in+progress%29)
"I happen to like very much my 0.25" cal Crosman 2200, but one of the things that can create havoc in a hunt is the noise;
and this gun's "stock" can make a LOT of noise.
It is hollow and plastic.
So walking through the thorns/brambles can really make some noise.
¿Did I mention that the butt can make NOISE?"

Gun was made by Jeff Wolgast (http://www.network54.com/Forum/79537/message/1134589746/Gun+was+made+by+Jeff+Wolgast)
"So we embarked with Mike Pearson (another of my American Compadres) and Jeff in the making of another pair of guns.
I ordered the barrel blanks from Tim (sort of "underwrote" the effort, partially) and had them sent to Jeff.
Jeff decided to make several more, I think 4 X 0.25" cal. rifles were made.
I ordered also a rifle in 0.20" cal. just to have tested the complete set.

Because there were no more 75 years conmemorative versions, we settled on the standard 2200 platform
(which is why I never suspected the noise factor would be such a nuisance).

This 0.25" cal. one is my keeper!
It fulfills a very precise shooting need (to shoot indoors and at close ranges at BIG, STRONG birds)
and I will put it to the test with Iguanas this weekend."

Iguana Hunt in Mexico with a .25 Pump Rifle (http://www.americanairgunhunter.com/iguanahunt.html)
"As most of you know by now, my Pigeon-Gitter is a 2200 Crosman pump up changed to 0.25" cal
and tuned by Jeff Wolgast and then re-tuned by me.

2.- For the guy that was asking about quality pump-ups, this should be proof enough that you can get
a quality gun for less than US$250.00."

"I had four of them, one in each caliber from 0.177" to 0.25" the only one I keep is the 0.25", deadly pigeon medicine."

Héctor, I done a lot of shooting of Eurasian dove.
Certainly not a bird as robust as a pigeon.
But, the general anatomy is reasonably similar.
But, a challenging target none-the-less to take humanely with a .177 off-the-shelf Daisy 880 using 8-strokes of compression.
(http://rimfirecentral.com/forums/showpost.php?p=4696168&postcount=13)

I've found the best way to eliminate a fly-off is to damage the flight muscles and/or wing in-the-process
of penetrating the lung(s).
To this end, a broad-side hit in the #3 area with the POI entry wound at the junction of the wing-root
and body causes sufficient injury to the flight muscles and wing skeleton to render the bird incapable
of flying to escape.

As such, the Eurasian dove drops after being shot.
But, may not expire within 10-seconds of being hit.
However, a lung-shot would not be expected to result in instant death.
It may take a little longer ... but, it is a fatal shot.

A back-shot will accomplish the-same-end by damaging wing up-stroke muscle and penetrating to lung/heart area.
Once again, the bird is incapable of flight.
But, death may not come within 10-seconds.

I've also used a .22 caliber BSA Lightning XL to great effect on Eurasian dove.
(http://www.rimfirecentral.com/forums/showthread.php?t=432106)
And, a .177 caliber BSA Lightning XL
(URL="http://www.rimfirecentral.com/forums/showthread.php?t=431928)
But, over-penetration becomes a concern.

It would be great to have a .25 caliber MSP such as Hector's 0.25" cal Crosman 2200.
But, I don't know of anyone performing such conversions.

Hello Alejandro!

The Dove is sort of a half-scale pigeon. In this context, smaller calibers and even less energy is needed.
Not that a larger cannot or should not be used, by all means, always use the best tool at hand.

Doves are usually regarded as wild birds. Pigeons on the other hand, are now mostly associated with human activity. Whether it is a grain operation, or a stable, or a church. It is easiest to find pigeons associated with human activity.

Usually, we airgunners face off pigeons as part of a pest-control operation. And in MOST of those cases, the proximity to humans makes it absolutely essential that no animal goes to die somewhere else.

So, yes, we have to be very selective in our shots taken and how we approach the animals.

And we need to take into consideration the 10/10 rule because while other situations will lead to the pest's demise, it may also spell the pest-control operation's demise should the public come aware and take action.

Your shots are good, and in the condition of a wild, non-native dove, it is a great suggestion!

Thanks!

Un abrazo!

So Héctor ... Is there anyone performing .25 caliber conversions on Crosman Mod. 2100/2200 MSPs?

Hello Alejandro!

Sadly, no. And the reason is simple: Crosman does not make the 2200 anymore.

The 2100 was never powerful enough (16 ft-lbs needed) due to its smaller contained volume.

I've been working on an alternate route, but that still needs some experimenting and right now I am busy with finishing other projects.

Keep well!

...............................................................................
The heart really lies where the #26 is pointing to.
Much lower than most shooters aim at.
...............................................................................
The other day, I had a shot at a Eurasian dove high-up in my backyard pecan tree.
The shot was angled from the underside.
As such, my preferred POA/POI was not presented.

So, I made the conscious decision the try for a #26 POA/POI pellet strike.
However, I was very concerned about a potential fly-off because a
#26 POI does not damage the wing/flight muscles.

However, I was determined to better-aim and hit the heart region.
When the shot from my Daisy 880 hit its mark ... the Eurasian dove simply collapsed.
And, plunged straight-down to the ground.
I began counting the seconds ... one-one-thousand ... two-one-thousand and etc.
Until the bird was clearly expired ... took about ten-seconds after being grounded.
And, before the cats I feed my kills showed-up to claim their prize and clean-up.

The #26 heart shot is one I normally don't try-for ... it is too small of a instant kill-zone
with less latitude for error
Especially when using a low-powered MSP.

Had I used my .177 BSA Lighting XL ... a near-miss would have still penetrated deeper - upwards towards the lungs
and further through to exist the back damaging the up-stroke wing muscles.
Sort of a reverse back-shot.
