Use havalons, opinel, kershaws, buck to gut and cold steel, dexters, forshner, victorinox etc skinners, deboners
What .308 cartridge you're using? We mainly use 2 the 130 gr speer HP and 165 gr Sierra Gameking HPBT. The 130's are used mostly for our small 30's up to 300 wby. The 165 is used mostly from 300 wby up to our big 30 cal wildcats. If going for pig with our smaller 30's we use the 165. The 130's are strictly for thin skinned game like deer, goat etc The 165's we've used all over the world including 100's of african game.
Goodluck on your hunting journey!
Aloha n good shooting!
