quick load assistance please

[chet]

I sold a rifle, the buyer didn't want the ammo. Now I have a buyer for the ammo. I want to get a general idea of how close to max this ammo is before I sell it. Obviously it was safe in the rifle that it was loaded for, but I'd feel better if these happen to be a little on the mild side........
