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.
