Thanks ClapperZapper, I have the back issues of The Double Gun Journal, will look it up.I have a 28 BORE James Purdey double rifle cased with all original accessories and mold now and used to have back in the 1970's a Holland and Holland 12 BORE underlever hammer double rifle that weighed 16 pounds and was regulated for 10 drams of blackpowder cased in almost new condition with all accessories.It was a one off experiment made for the Nawab of Bhopal. My 28 BORE takes a modified .577 Snider case and I am reworking them now. A friend of mine has a 16 BORE Holland and Holland double rifle regulated for 9 drams!I like those oddball BORE double rifles!
