And I was going to say normally the 3" uses a 750 gr and the 2 3/4" a 650 gr and am instantly proven wrong.

Nice old hammer cape gun.

So Rolf Babnicks modern Greener Empire Cape gun conversion in 12-bore and .577 2 3/4" has some historical precedent. I always thought a 12b and the hefty .577 unlikely, unless one was pot shooting pheasant and wild cock in an Indian jungle where a tiger, gaur or rogue elephant might be stumbled onto. If ones gun bearer fled!

The choice of the .577 however was to fit better the large action of the 12-bore.

Back in 2004 I thought the price was high ... Now I wish ... Though it is just a cape gun.
