Your target loads should work well with a comparable weight hunting bullet. Just back down a bit on the charge and work back up. Pressures with a given powder charge might be higher due to the relatively increased bearing surface of the hunting bullets, but they should be easy to stabilize. This cartridge is in the .260 Remington to 6.5x57 class and should make a fine hunting cartridge as well as target round. If you get a load you like, please share it with us here.
