Hate to see you chop down the 410 because they are a little rarer than the other guages, if you cannot find another barrel for it, you might consider looking for an old remington 870 or mossberg 500 or ithaca 37 or something like that in 20 guage and chop it down. It will have a little more recoil than your 410, but not near as much as a 12 and will be lots easier to find one of these. A 28 guage would be good too. but they are kinda scarce also in the low end pump arena. More in the nice double end of the spectrum for trap and skeet. Good luck on your search.
