I also been trying to pick up a few boxes of older cal stuff, 250, 300 sav. 38-55 win. Speaking of ammo, I have older paper shotgun shells that have the flat crimp ends in great collector condition. Some day I need to get a book to see how old they are and any value?? Mostly in 16 and 20 ga. They are probably 40's-50's but only a guess.
