I don't think so... That it's a fool's errand, that is.

I have been hunting grouse & woodcock for more than 30 years, and I use a 28. A S x S W.J. Jeffery BLNE, 4 pounds 5 oz., and I LOVE it.

Easy to carry over the miles, and very quick to get into action. I would not want to try shooting driven birds with it, but for snap shooting it the thick stuff, I have found nothing better.

But I doubt that you will find an O & U quite that light.

BTW - Larry, I have one of those A & F Rizzini-Zoli guns in 28, it weighs 4 pounds 14 oz. Also a S x S BLNE. A very nice little gun, almost new condition, and is prooved for 2 3/4" shells, but it sits in the safe whle I carry the Jeffery and 5/8 oz RSTs.
