Help! Trying to find out the value of all brass shotgun shells

I'm new so please be patient.

I have a full box (25 rounds) of what appear to be military shotgun shells.

The box is plain brown cardboard with no manufacturer's name on the box. The shells inside are Winchester. The Box has the following on top:
25 Shells, Shotgun
12 Gage, Brass
Smokeless Powder
No. 00 Buckshot
For Use in Hunting Small Game

Two opposite sides of the box have:
Lot W.R.A.-22003

There are no other markings on the box.

The shotgun shells have "Winchester No 12" on the primer end and "00 B" on the wad end.

The shells are in good shape. The box has a tear on one side but is serviceable.

Any ideas what these guys might be worth?

Thanks

I typically get about $250 for a box like this when I find them. Box condition has a lot to do with it.
I don’t run across them near as often as I’d like!

Thanks for the information. I appreciate your response.

Happy to help!
