I'm curious to know what you guys think about how the performance differs when you're swinging 28g barrels attached to a 20g frame. I've never had the experience, but I'm thinking about getting a 28g set of barrels for my 20g receiver. Cheaper than getting a new gun altogether, but is it worth it?
This doesn't have to be specific to 20/28. Would also be interested in any other feedback on 12/16, etc.
Thanks!

I think the biggest performance issues are weight and balance. Neither are absolute show stoppers. If you have a great lightweight 20 gauge you will love shooting the 28.

My SKB 20ga works so wonderfully for me I'd be scared to fiddle with it. Going 28ga couldn't be an improvement, for my requirements.
Jim's right re "showstoppers." In these cases, or my business, I usually say to myself "Would you buy it if offered to you for nothing?"
In this case, my answer would be no.

28 gauge barrels are smaller in diameter than are 20 bore; that makes them lighter if you compare like wall thickness and length. However, the 20 bore frame has a wider firing pin spacing which "requires" thicker breach walls on the 28 gauge barrels. Usually, the profiling to get the thick breach 28 gauge barrels down to 28 gauge tubes adds a good deal of weight. Also, the 28's will have to be spaced apart at the muzzle to account for the wider breaches.
Without serious "intervention," the smaller gauge barrels will weigh noticably more than the originals. This will move the balance point forward and will slow the swing. That is not necessarily bad, but should be considered/known.
I understand the "sI-rene song" of the mutli-barrel set. But, would suggest considerting that a 20 gauge hull can be reloaded to do virtually anything a 28 gauge will do. The advantage of petite action and svelt barrels of a 28 gauge is significently lost on a non-scale frame. This applies to all multi-gauge sets.
Frame scale is best understood by study of Parker frames; something like 8 to 10 frame sizes. Most gauges were supplied on a light, medium, or heavy frame for the gauge. That said, a 28 gauge on a light 20 frame makes much more sense than a 28 gauge on a heavy 20 gauge frame.
None of the above is intended to de-rail your project, only to spark discussion for your consideration.

Not much can be done about the numbers Rocketman discusses; the 28ga barrel thickness at the breech to match up to the frame is extra metal and that's all she wrote.
If the 20 ga frame is fairly small and light to start with, the small ga sets work pretty well. My experience is based on a RizziniB O/U multi-barrel set with 29" 28ga barrels. The Rizzini 20 ga frame is pretty svelte AND I can't hit much with a gun that weighs less than about 6.25 Lbs, so it works for me. I tried the scaled frame gun and it was cute as it was light, but I've failed in the past with similar guns and went with 20 ga frame/heavier gun.
If you do go with small ga barrel sets, consider longer small ga barrels that might balance better with the slightly heavier frame.
