Hi, Gents:
Just a little history. The .275 H&H had a few problems besides the lack of good bullets. It was a me-too cartridge, designed to compete with the .280 Ross. As Ross Seyfried noted in his article on the Ross in Rifle #187, Jan. 2000, the slowest available powders were equivalent to 4064, so I expect a few pressure excursions occurred. Then the death of Sir George Grey, when he failed to stop a charging lion with a Ross, sent hunters back to the .375 H&H and the big bores.
Bye
