Ron, et al
You have been very helpful in dating Remington boxes but - is it possible to accurately date Post WW II Winchester boxes??
If so, exactly what codes or numbers do I need to look for?
I’m fairly confident in dating the cartridges but there are many instances where the boxes are not correct. For example, I recently saw a box of SUPER-X 243 WINCHESTER (6mm) which would seem to indicate 1950s production but the cartridges had a WW SUPER headstamp which, I think, dates them to 1969 or later.
Any help would be appreciated.
