If I understand this correctly, it seems that you have installed a narrow, rifled barrel inside a smooth-bore shotgun, thereby giving you a tool which MUST be used with absolute accuracy, since the average varmint is not going to wait around while you reload for a second shot.
Watch out for the gigantic radioactive mutant squirrels!
But this time I cut at the chamber..n married the barrel permanant..
Very pleased with its accuracy..
First group shot with factory ammo..3/4" n followed by a 1/2" group 3 shot..@ 100 yds.
Gonna try some handloads to see if I can do better..
Real pleased so far... :0)
Fergot to mention.. chronographed at 3350 fps...
That looks like so much fun, Al. You get the "Shooter of the month." award.
Looking good Fig!! I really like how you've married the barrel up to the shotgun chamber.
Is the sight clamped onto the original shotgun rib or did you add a rail for it?

Milled it flat.. n drill n tapped..a flat base weaver scope mount on it.
6 screws in the scope base..tapped into the inner barrel
2 screws..mill..drilled n tapped through the base of the shotgun barrel as in the pic..
The under side of the varmint barrel milled flat..as was the shotgun barrel..
N.. the 2 mated via 5 screws drilled n tapped..
So it is pretty ridged..n locked in..
Lastly.. I milled..a gas relief port..in the bottom of the barrel in the breech..
In case of a pierce primer or case head seperation..
Not....that...i...would ever.....stress ah peak load... ;0)
No...no... not me...!
We well see what we get with the next loads..on the graph...Will be...mebee this weekend... ;0)
