There are a lot of bullets available for reloading the 10.75x68 Mauser. Here are a few I have but have not tried all yet. The longer bullets might not work because of their length.

Woodleigh 10.75x68mm 347gr FMJ, Woodleigh 10.75x68mm 347gr RN SN, Woodleigh 404 Jeffery 350gr RN SN, Woodleigh 404 Jeffery 400gr FMJ, Woodleigh 404 Jeffery 400gr RN SN, Cutting Edge .423 Cal 325gr Safari Raptor, Cutting Edge .423 Cal 250gr Tipped Safari Raptor, Swift 404 Cal 400gr A-Frame Semi-Spitzer Soft Point, GS Custom Bullets .423 Cal 387gr FN, GS Custom Bullets .423 Cal 320gr HV

The two I want to try are the Cutting Edge .423 Cal 250gr Tipped Safari Raptor and the GS Custom Bullets .423 Cal 320gr HV.
