I have no more information then they were fired from a .30-30 rifle, lever action I think but maybe not. My daughters boyfriend who lives 800 miles away sent me this picture. I don't know that type of ammunition it was I think he said Remington. I do know he said it was new ammo right from the box and that it was the correct ammunition for that rifle.
To me it looks like .30-30 ammo fired in a .38-55 or .375 Win. I think someone is assuming that the rifle is a .30-30.
All I know for certain is that the rifle and the ammo are not the same caliber.
