I shot a Remington rolling block and Siamese mauser in .45-70.The Mauser will handle a 500 grain cast bullet at 1800fps.That load should kill about anything.

I remember when gun magazines were advertizing those! Wish I could have gotten one.
I did end up with a 1897 7MM Rem Rolling Block which I had converted to a .444 Marlin as it was the only conversion kit (Numrich Arms) I could find at that time. Not real accurate as the twist is not tight enough.
I also remember when the magazines had Martini Henry rifles for sale.
