I just had a shooting weekend. Watson577 was here with his 8 bore A. Henry rifle. We spent all day Saturday working on loads for that beast. Here are a few videos of me shooting it (my first ever shots with an 8 bore rifle).

The rifle is 14-5/8” pull, which is too short for me for a hard kicker, even with the slip-on rubber pad. With each shot I got slugged in the nose with my thumb. Other than that, it’s not worse than my .500 NE Merkel. This rifle is just over 16 pounds.

The load was 9 drams (246 grains) of black powder with a 1250 grain paper patched conical bullet. This rifle uses the 3-3/4" case. It's a big cartridge!

Edited: The case length is 3-3/4". My original post said 3-1/2".
