My local gunshop has ONE box of original Winchester yellow box 348 Winchester ammo for sale. The ammo is on consignment at $45.00 (no sales tax in Montana).
The bullets are the 200 grain Silver-Tips and I inspected several of them and no tarnish or defects seen.
The box is in okay shape with some tatters but the ammo was sure clean - no water spots on the cardboard.
I am not at all sure what 348 ammo goes for (out of my area of interest these days) nowadays but I have seen a few "WTB" ads for 348 ammo here and on other sites.
The shop is closed Sundays and Mondays but will open Tuesday morning at 9:00 A.M. and their phone number is 406-683-9844
Hope this helps someone.
