If the barrel is not to thin you might be able to have screw in chokes installed in the barrel.
It might be less expensive to just buy a new barrel or find a good used one.

As for shotgun barrels having holes in the pattern. I had a beautiful A-5 Browning that would pattern 6 shot as pretty and even as possible, try using 7 1/2 or 8 shot and there was holes in the pattern big enough to throw a ball cap through.
You might want to try a different shot size before you give up on the barrel you now have.

You will be money ahead just buying a new barrel with screw in chokes.

Unless the bore was mechanically wrecked in some manner as a result of the "boring", you should be able to adjust the load to the barrel. Shotguns are no different than rifles, you can't expect to shove anything you want in the back side and have it work properly on the front side. Change the powder, change the payload weight, change the wad, ect. The amount of squeeze applied by a common constriction choke often means less to degree of pattern quality than a properly built load for the gun.

Even shotguns are not immune to the basic law of firearms:

EVERY gun/barrel/ammo brand & type combination is a law unto itself.

Case in point: Shooting Budd & I both have Maverick 88 shotguns with the 18-1/2" cylinder bore barrel. Mine throws the best patterns with Rem #4 Buck, while his works best with Win #1 Buck. Another Budd with a Mossberg 500 and the short barrel finds his is best w/Fed 00Buck.

"Slugs?" you say? Again, Your Mileage Will Vary. Mine best with PMC brand 2-3/4" 1-Oz, worthless with Rem "Sluggers". First Budd's is best with Sluggers, while 2md guys guns like the Brennekke KO slugs.
