Seems a little pricey IMHO ,although folks will pay good prices if they really want something.This ammo has not been out of production all that long ,and will bet there is plenty of it stashed away.
I saw an auction where the seller had 1 box of each in 45 Colt ,30-30 and 44-40 and wanted $165.00 US(for all 3) buy it now ,but I think the winning bid was $ 146.00
Collectors who pay good cash, want the box in mint condition ,as the silver finish scratches very easily.
I myself have several full boxes of 30-30 and .45 Colt ,blasted off a few boxes of each and have a few for old time sake.
Cheers
