Jawjadawg,
Several different points need to be addressed. First, is your 20 gauge safe to shoot now with the pitted chamber? If its still safe, then it is a cosmetic issue. Second, you should really get a set of Gauge Mate Golds and see how your gun shoots with them in. You will be surprised how well it works. Out to about 30-35 yards it will work very well. If you want to shoot a 28 farther than that you need a full length 28 gauge (bore?) barrel and tight chokes. Third, if you sleeve the barrels,and I ASSUME you are turning the barrels into a mono block and putting on new 28 gauge barrels, will this change how the gun handles? Only an excellent sleeving job, such as by Mr. Merrington, will retain the gun's handling properties. I would put on 30" barrels, but I like long barrels. I have handled re-sleeved guns that were very muzzle heavy compared with the original set of barrels. And finally, is this worth it financially? If money is no object and you are not concerned about resale then have at it. You can also have new 20 gauge chambers sleeved into this gun, retaining the barrels.This would be preferable if it is a high end gun. I shoot some 3/4 oz reloads in my 20s and it kind of makes the 28 gauge not so special. I am a 28 gauge fan, so I still own them as the little red shells are cool. If these are truly spare barrels, I would get them re-barreled to 28 gauge to make a 2 barrel set as long as they will handle well. That would be very cool. Please keep us informed as to how this project progresses.
Regards,
Jeff
