[quote=“Lew”]That makes sense. The bullet diameter including the paper is 0.462" so .461 Gibbs sounds right. What is a Gibbs #2??? What rifles was it used with?
George c Gibbs was in Bristol and bought the patent to make Farqueson single shot falling block rifles. (think of the Ruger no1) which he did until the patent ran out. The rifle was a contender in the trials which saw the Martini adopted.
Gibbs hand made his rifles to a very high standard but only around 1000 were made in all calibres. I’ve no idea what the number sequence signifies, I would speculate it might be loading / intended use as the .461 had a double life as a target and a big game calibre but only in small numbers. That would make your round quite rare I would imagine.
The rifles achieved some considerable success in the target shooting world, as did Gibbs himself, and the No1 was the favoured round among the highest level shooters apparently for some time.

I drive past Marlborough on the way to my son’s house, I might go and look him up.
