max. base diameter for the 10,75x68 is 12,57mm so there is no case for an easy conversion. btw, the 8x68 have a max base diameter of 13,00mm. unfortunately since RWS has dropped this classic round 20 years ago now there is no mayor ammo maker for this round. horneber make brass but only from time to time.
I dont know if the website is up to date but here in was a Gustav Genschow with scope for 6900 danish kroner, under 1000 euro iirc

12,57mm ie: .495" (12.573mm) might be close enough (in the average chambers)to allow .45 basic brass to be used, which is nominally .500" at the base. The rims need to be turned off, of course, and new extractor groove cut - simple stuff with a small lathe, along with the necking necessary - plenty of dies available for that - even .416 Rem dies would probably work as forming dies and the seater might work as a final sizing die. Measurements must be taken to see for sure. It may need polishing or reaming in the neck area.

.68mm is 2.68"(6.81mm) would be easily made from the basic brass - if the chamber allowed the slightly larger diameter- which is likely. A person should measure .416 Rem brass in front of the belt. Belt needs to be cut off and rim cut to desired diameter.

10.75mm - .423" bullets might be a problem nowadays, but a hard cast bullet 350gr. to 400gr. at up to 2,200fps would be decisive.
