WELL IM FINALLY FINISHED

Modifying a  MOD 130S Vortex QE Breakbarrel  it is a smooth bore 8mm shotgun. Here's some of the ammo. A paper casing. Holding 47.3 grains of shot The casing weight is 1.7

    My concept is from the civil war. Buck and ball loads. But has been modified I also use it in my 28 ga Muzzleloader shotgun, the sabots are larger and use heavier gauge paper casing.

 The cartridge is a thin piece of tubing made to 8mm  there is a  wad in the breach end. The case is cut in ten places around the top for crimping. They are filled with shot. Then they are crimped and a small drop of dopp wax keeps the crimp closed. 

When the gun is fired it compresses the wad splitting the paper casing and opens the crimp. The barrel is slightly choked further opening the casing as it leaves the barrel

I had made some sabots in the 7.62 pellet size they shoot well in the rifled barrel of my MOD 130S Vortex QE and have a good spread up to about 30 or so feet more than that it will probably be ineffective.

 Purchased another MOD 130S Vortex QE Breakbarrel to modify. My other is broke in and it's very fun to shoot.

I will be updating all of you soon on the progress, testing etc of my project shotgun.

I finally got to shoot it once. It gets dark so early. I will be shooting it extensively on Monday. This is from 15 feet.

Here are some pictures of the shot patterns. I'm not totally happy with the way my first sabots are working and have a couple of ideas to make them better.  I will be making some new prototypes and testing them using a lighter wad material and another crimping style. I have 25 more of the first batch of sabots to test also.

Using my new sabots I shot my Hatsan 130QE 8mm smooth bore shotgun today it tested at 540fps shooting 37grain 9 shot. Here are the results.

I'm looking for something to use in my barn to whack starlings that try to nest there. How effective is this? Right now I've been using .22 caliber snake loads out of a pistol and they don't have much range at all. I don't want to up my game to say a .410 because I'd risk damage to the barn. From your pics the shot pattern doesn't look so good from 20 - 30 feet which is the distance I'd probably be shooting (the sweet spot if you will). Barn is 36 feet long with a roof that peaks out at about 23 feet.

My son and i tested it against a .22 long shot shell they are a joke and good for about 5 feet. I'm sure this would kill one at 25 feet. The shells contained 37 grains of shot. You can load up to 47 grains of any size shot or buckshot you want. The rifle was a refurbished Hatsan 130QE .30 caliber $169 and if you don't do the reaming and polishing the barrel yourself it would cost a couple $100. I did my own modification's.

So is the barrel length stock? It looks short but half is probably thhe brake. So you basically removed the rifling and polished it smooth and then roll your own shotshells? I'd be interested in the shotshell making process. I can ream with the best of them. Might be a good winter project. How is it cocking that thing with just a 10" barrel??

The cocking isn't all that hard. I'll probably make a PVC pipe cocking aid..

I will make you a tutorial on how I make the shotshells and send it to you in private message in the next few days

Don't want to hijack the thread, as it is an interesting thread but, if you are looking for something that will kill up to pigeons, but yet not penetrate the "tin" roofs of barns, I would suggest a Dragonfly in 0.22"  shooting pointed pellets at about 500 fps. That may mean two, maybe three pumps.

IDEALLY, as my experience taught me, it should be a 0.25" cal MSP, but the best approximation in current manufacture is the 0.22" Dragonfly. Pointed pellets need little energy to penetrate and the "large" caliber (for feather), will make the pellet STAY in the bird. Starlings are relatively "soft" targets compared to pigeons.

 

The shotgun conversion is interesting, but in my mind, the main application would be a mini-skeet game. Maybe using some cheap glass balls as those that are used for ornaments of Xmas trees and are so inexpensive, ye festive and colorful.

Or perhaps the Shatterblaster type of colored gypsum discs.

Again, JMHO.

The birds I need to whack don't always sit still. Barn roof is OSB ply with shingles on top. Side walls are also OSB with cementious siding over them. While all the glue in OSB makes it pretty tough, my wife doesn't like the thought of pellets embedded in her horse stable.

Ya since this is about a shotgun mod. And not a bought pellet gun post. Kinda hijacked.

And I also killed a collard dove just this morning at about 25 feet. His partner escaped to bad.

I didn't make the gun to be a target gun. Now that I've taken a animal I've proven to myself it is capable of doing so. Some of us just buy airguns while others mod and create. I am the later.

410 shotgun. The muzzle velocity is nominally 1830 fps. ranges not exceeding 50 yards (at the very outside).

So my mod that averages 540 fps will easily take a bird or small game at 20 to 25 feet. 10 yard at the very maximum.

The Crosman "2500" in the picture was made by re-barreling  a Crosman 2200 to 0.25"cal using a L-W barrel. Modifications were somewhat extensive (pump pivot point, bolt head,  bolt probe and seal, loading channel, pumping linkage and pumping head/seal), but the results were good. Accuracy was excellent out to about 25 yards. And terminal ballistics didn't change much between a straight up 4 yards shot, or a 20 yards across the room, but up into the rafters shot.

I can understand your wife, this gun was built to be used in Racehorse stables in Mexico City's "Hipódromo de las Américas", where the horses slept in a 5 story building with elevator, AC and running water.  Some of those horses were worth more than a mansion. You can imagine the customer (the Racecourse), was very demanding.

Again, the trick is to make the pellet stay in the bird. And that usually happens at around 500 fps MV with a "largeish" bore pointed pellet.

Starlings are active birds, yes, but they do settle down at some times of the day, just like pigeons; and we used to do the cleanups after dark.

You have not told us the dimensions of your venue, so, perhaps the Hatsan Shotgun mod is adequate. In that case, I stand corrected, apologize for my intrusion and take my leave.

I can understand Hector's recommendation for the Dragonfly.  It's a very capable platform.  I made one modification to mine.  I replaced the rubber bushing behind the piston head with a non-compressible nylon spacer.  Seemingly, that rubber bushing was engineered to dis-allow over-pumping, since it expands and increases friction as pump pressure increases.  Here are some numbers with .177 7.9g pellets after replacing the rubber bushing:

3-670

4-740

5-780

6-820

7-850

8-870

Low power on low easy pumps is to me one of the most endearing features of the Dragonfly.  I shoot it all the time in the basement at 3 easy pumps.  A 7.9g pellet going under 700 fps will take out a pest, but do no harm to a tin roof.  It doesn't hurt that the gun seems remarkably accurate with a Williams peep!

For specific indoor pesting, I would probably opt for .22.  More thump with even less velocity.

The starlings in my barn nest in the soffits. They land and sit for a moment and disappear into the soffit. Now I could plug all the soffits but it's not a ladder job I relish. Shotgun route seems a better option. I have a Diana 27 that is a tad over 700 fps and a Slavia minuteman that's 350 fps in 22 cal. I also have Benjamin and Sherican rifles. They don't sit still long enough to take aim and place a good shot.

Not fixing the soffit is not an excuse to play airguns Bill.

 

The velocity is ok-ish, #9 isn't impressive at any velocity.

What next?

Cut open some 7 &1/2?

There you have it, the world according to John.
