Are Winchester and Ww the same cases?

[Fatelvis]

I aquired some 222 cases. Some have Winchester on the headstamp and some have WW, (Winchester Western). Are these cases the same and therefore interchangible? Or should I keep them seperated. Thanks-

Two different animals from the same barn.

Size'm, trim'm, and weigh'm.

If they weigh the same, they are the same.
If they don't, they aren't.
