Not sure I'd want a 5 1/2# 20, but I have a pair of 6 1/4# Brit 12's. Have used them on pheasants in Iowa and the Dakotas this season. 1 1/16 oz R barrel, 1 1/8 oz left. Would not want to shoot a round of skeet with those loads, but if I shoot more than 5 shells in a day chasing wild pheasants, that's more than I should be shooting anyhow. No problem with those guns and loads under those conditions.
