my brother in law gave me some ammo and I do not know what it is. I thought it was 8mm but case is smaller and not as long.

I had someone tell me this is 303 made in Portugal , is it good ammo and what is it worth?

8mm would not be rimmed and 303 has a rim. The headstamp is Portuguese .303.

thanks

8x56R is kind of what it looks like but can't see the case well enough.
