Frame size and barrel regulation

All the best Dave.

And of course, the 1 1/2-frame guns which became very popular and common at about the turn of the century and eventually replaced the 1-frame.

I suspect they would all shoot about the same as only the barrels and chokes determine how a gun will shoot and pattern.

I have had this same conversation a few times. The bottom line is that shotgun barrels on double barrel shotguns are not always straight, almost never on "good" guns. I have been beaten to death by so called experts on this subject, but I am sticking with my original statement. I have a Lindner pigeon gun that is so far separated at the breech that it could have been made as an eight gauge. The muzzles are much closer. These barrels cannot physically be straight. They are swamped in like a double rifle, however little.

Can they be straight? Measure the center to center distance at the breach end and at the muzzle on any double any gauge and it will be different from end to end. If they were straight, the right barrel would shoot to the left and the left barrel to the right.

Thanks, Chris. Dragging out my #6 frame ten gauge right now violates my doctors instruction, but I will guarantee that the center to center at the breech is a whale of a lot bigger than the center to center at the muzzle. I will take back what I said about swamped barrels on double rifles, but I'll stick to what I said about shotguns.

Place barrels in vice (carefully) sight the sight on a doctor pepper can , & both barrels should be looking exactly as each other at 30 too 40 something yrds. At the can. (This requires a Parker with un cut barrels)
My two cents worth

That's a great idea. Like bore sighting a rifle. Remember, you have to back way up from the breech to make the target a very small image. However, I would place my barrels in a vise, rather than in a "vice".

Oops
vise
meriden vise at that!
Thanks
