Cutting SXS Barrel - Crown Or No Crown

[A Cleaner]

Ok, I've tried to do my homework searching previous threads so as to prevent a repeat. I found info on cutting single barrels and crowning them. I found info on cutting double barrels but no crowning info.

My Question:

When cutting down a SXS barrel, can each barrel be crowned or will the end just have to be squared?

Also, does anyone have any experience with having a SXS cut down that can correlate crowning vs. squaring to patterning/accuracy? I know that I will be "unchoking" the barrel to cylinder, I just don't know if I can expect each barrel to perform the same as a single factory-crowned cylinder bore.

Thanks.

1. What kind of SxS ?

2. You interested in selling it instead ??? (I hate to see old SxS shotguns get cut up.)

The cut should be made on a vise fixture with a guided fine tooth hacksaw.The cut needs to be measured square and taped. The inside and outside of the tubes should be lightly chamfered, evenly with no chatter . The inside of barrels should be LIGHTLY honed (polished ) with a flapper of a couple grades of fine emory at a few hundred rpm. You now have no choke, and if done correctly nothing to deform a pattern.
If the rib is hollow the slickest thing I've seen and had done is to pour in some hard lead alloy mixture from a casting ladle. This should make sure nothing has become unsoldered and the end sprue will file down nice and flat. Most don't touch up blue but leave the muzzle in the 'white'.

Scout...Stoeger Uplander...it is a used gun and has endured some wear so I'm not cutting the pristine barrels that some might imagine. Thanks for the offer but I'm gonna pass.

Gordon...that could not have been more complete or concise. Thank you so much for your input.

Any other input is eagerly awaited and readily accepted.

Why not save the longer barrels (esp. if they have choke tubes) and order a Coach Gun set of barrels? You can have your gunsmith fit them to your receiver (Uplanders & Coach Guns use the same receivers) & still retain a lot of versatility....

I cut-down a Stevens about 15 years ago using almost exactly the technique Gordon described. Someone had left it standing barrels down on a cement basement floor in the back of a small closet forever. The front of the barrels were heavily rusted. I paid about $100 for it & the shortening to 18 1/2 inches worked just fine. I eventually sold it. Have a Stoeger Silverado Coach Gun now.
