Not that rare. I have a supergrade 270 and 30-06 in featherweight. Wrong! - All though .270 and .30-06 were of the two most produced calibers, the order of model production (in volume) went from standard grade to featherweight to super grade to supergrade featherweight to custom. The production date of the particular piece is important with those produced in the '60 as being the least desirable and those from pre WWII and post WWII being the most desirable.
