Thanks to Ron Merchant (and lots of help from John Moss!) we have a great piece to help figure out dates of Remington boxes posted on the IAA site.
This one is in .pdf format and is about 6MB so it may take awhile to download.
We already had one to date Peters boxes.
Who can do one for Winchester boxes?
It should not be the "every box ever made with every variation in every caliber- there are books for that sort of detail. What is needed by most newer collectors is just something that will narrow a particular style of box down to a 5-10 year window. That can probably be done with 25 boxes or less, and they do not have to be the same caliber. Limit it to centerfire calibers if you like.
A lot of people just want to know what would be a good match for their rifle made in a certain year, and eventually they may get enough different rifles (and ammo) that they become cartridge collectors.
