8mm Hatsan shotgun mod

[Septicdeath]

WELL I'M 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’m betting you will have a great working mini shotgun! Can’t wait to see some patterns.

That’s pretty sweet! Hatsan is gonna steal this one from ya. Lol. Can’t wait to see how it shoots.

I was able to shoot it once because 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.

The 15ft group looks useable. What was your inspiration behind the build? Squirrels? Targets? Just because you can? Lol. Not hating. I think it’s cool. Just wondering what your shooting for.

Because I wanted to build a break barrel shotgun. I will use it for everything you just said. I think after I tinker with the shot cartridges I will attain better patterns. I have already started on 3 new prototype cartridges to test. My hope is decent pattern at 25 ft.

I am also working on a ckoke for the barrel that can be threaded on or taken off.

Tested again today with new prototype sabot.

Nice groups. There’s definitely more shot on paper. I’m assuming that’s a normal piece of 8”x11” paper. That last 25ft one looks like youre about where you want to be. The choke would probably tighten it right up. What size shot are you using just out of curiosity?

It shoots a little high. But we figured that out.

Have loaded with 9shot I will be testing other shot also. You can use any size. I just don't exceed the grain weight of 46.3 grains of a H&N 30 caliber pellet the 130 QE was designed to use.

That’s what I figured. As long as you keep the weight around stock pellet weight. You could fire pretty much anything. Kinda like the PBBA air shotguns on a smaller scale minus the pcp equipment. I’ve had my eye on one of the shotgun pistols for awhile. Just having the extra $1500 to blow. Sorry off topic. Just day dreaming. Lol.

New second generation sabots.

Why do you have two threads about the same thing, then keep adding to both with the same posts?

Just curious.
