What were the barrel lengths of the original H&H bolt actions in .375 H&H? Wat years of study did they do with their African professionals and African hunting sportsmen that came up with "ideal" barrel lengths for steady aim, balance, swing and fit? I don't think the Animals or terrain have changed so much over the past 100 years. I read about the testing by experience the fine rifle makers did when developing their styles and ergonomics.
My .375 H&H (not short .375 any other mag.) has a 24 inch barrel. It balances well. It is a 1950's era FN commercial. My 9.3x 57 and 9.3x62 have 25 inch barrels (+ -). They balance well and carry well. I doubt that chopping off three inches or 4 will make a lot of difference in carrying. I do think it will make the rifle but heavy and will not settle on the target and sights as naturally with the shorter barrel. MHO.
