Going to a .375 bullet makes it legal for DG in all African countries, and you can use it in any long action like a standard Mauser action and have good magazine capacity.
The ballistics will be the same as a 9.3x62 and as far as I know you will have lots more bullets to choose from when using .375 bullets.
yes i know that but it just seems a lot to do for little gain. if you get around to it let me know as it would be interesting. i will just stick to my standard 9.3`s for the time being and let you do the experimenting
