Old 36ga two inch shot shell?

[OH Osthaus]

don't forget - you are measuring 2 inches on a loaded shell

the actual measurement of a shell is its fired/unloaded length

[Bill Murphy]

Actually, .410 shells boxed and labelled 2" are 2" fired length just like every shell made since. The number on the box is the length of the shell after firing. I measured some 2" .410 shells and they are 1.75" before firing. As Rick mentions, these may not be 2" shells as marked on the box, although such shells do exist. Too bad the box pictured does not mention shell length. They would be quite valuable if they were real 2" shells.
