Custom mod shotgun.
I'm working on a rifle now. It should be done in a few weeks. Modifying a Hatsan .30 caliber break barrel. When it is done it will be a smooth bore 7.874 shotgun choked to 7.77 Here's some of the ammo. A paper casing. Holding 47.3 grains of 6 shot around 21 pellets. The casing weight is 1.7
How did it shoot? Good pattern?
