It does seem that double rifle prices are declining. I remember a cased H&H Dominion grade in 500/.465 that was on Mike Schwandt’s website for high 30’s at one point and then later was offered in the low 20’s. I think doubles just got well ahead of themselves on price and now it’s time for a cooling off. The really desirable stuff (peachy vintage Purdey .375 and .465 etc) is probably holding its ground pretty well however.
