Thanks, that picture was taken before the rifle had been hunted much.
It is a.405 WCF TD and has had the chamber extended to handle 400 grain Woodleighs crimped on the cannelure.
BTW, there has never been a need for more than two shots on big game with the .405, much less 8, so I will just save my ammo and wisecracks. I also shoot a .405 double, so I would be competing against myself and could not bear to lose either way.

If you like my 1895 .405, you should meet Peter Richards up Port McQuarrie way. His has a scout scope on his and has taken a lot of big critters here in Texas and down under.
