There are not many 8 bore videos on youtube especially ones that show the guns in good detail but I ran across this just now.

I thought Craig Thompson might find it interesting since he tests 8 gauge buckshot loads. Im surprised how well proportioned it looks with 27" barrels. Im assuming it was intended to use buckshot since it choked full/full any thoughts on that ? I couldnt find any information on the effectiveness of buckshot for alligators, but I did find ballistic gel test that showed 00B averaged around the same penetration as 22lr which is commonly used on alligators for headshots. I think it would be easy to say this 8 bore probably has some interesting stories
