An interesting "study" into the 10.75x68.

At one time these were quite "common" on the second hand market. Cheaper as well probably due to the cartridges lesser performance and the Mausers being standard actions.

Harry Manners had a 10.75x68 and rejected it for a .375 for buffalo culling and elephant.

The weak bullet construction was often blamed for the lesser performance.

A 347 gr at 2100 fps or less is anaemic.

I noted Woodleigh made a 347 gr SP for the x68 and a 350 gr for the .404. I wonder if the 350 gr has different construction? The sectional density is also a little low.

If modern powders could get the 10.75 with a 400 gr up to 2,100 fps, it would be an acceptable killer.

I'd love to see a 10.75x68 as an acceptable big game cartridge. A .404 is however a far better choice.

The 10.75x68 reminds me of the 9.5x57, a milder cartridge, perhaps a little less powerful than sensible. But good for medium and driven game.
