I had one for awhile in .22 Hornet, it was a nice rifle. I don't think they get a lot of press because they're not the traditional side lock action people associate with Sharps. I don't think they're any lighter or less strong than the '74. I recall a story of someone loading his .50-90 '75 to .500 Nitro levels and using it for Cape Buffalo.
My '75 Hornet was as accurate as the sighting allowed it
