OK here is the promised pics of my "new" big bore. Not exactly new as it dates back to 1875 but it should turn out to be a shooter and I hope great fun.

It is a Martini Henry Rozier .577/.450 which was originally loaded for blackpowder. This rifle was built as a sporter and Rozier (or Rosier?) was an Australian gunmaker or assmebler based in the Colony of Victoria.

Points nicely and hopefully will shoot as well. If I can get it shooting hopefully will try it out on a pig or two this year.
