I am wanting to shorten the bbl on my 20ga. single shot.
Since my 12ga. sees all the action this would be basically a play toy.

My questions:
1. How do you recommend smoothing after cutting?
2. What will this do to my pattern?
3. Would an aftermarket choke be beneficial?

I know just enough about shotgun barrels to be dangerous, but your plan to cut the barrel shorter I believe will leave you with no taper inside, or a cylinder choke. If you planned to add a choke to your new shorter barrel, it's going to need to be bored and threaded to accept them, and the $100~150 it costs to do this makes this cost prohibitive in most cases. I'd suggest living with the new no-choke short barrel, or buying a new, shorter barrel with improved choke bore.

Also I understand that 18" is as low as I can go without NFA.
Is that measurement from bbl end to end or throat to end?

from breach face to muzzle. close the breach and drop a rod down the bore mark and measure and add 1/2" for good measure.

I sawed off the barrel of my Saiga 12 with a hacksaw, cleaned it up with a belt sander and used a spherical stone to brek the inner edge of the muzzle. Be aware that if is a gas gun you may have some cycling issues due to reduced dwell time. For my S12 i just drilled out the gas ports. In a brief patterning test i did not see an issue with 00 at 20 yards.

TIP - don't cut it less than 16" for a FBI agent.

Too bad the pics are too blurry to see how smooth it is, using only a hacksaw and a dremel.

Got to go shoot it now.....
