Frame size and barrel regulation

[Chris T.]

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
