Any poly tipped match bullet, or non pointed bthp will work well down to 1800-1900 fps. 108 eldm are reliable killers, 95 tipped match kings are excellent. 105 hybrid too. The 6mm with 2950-3100 muzzle velocity are really underrated hunting cartridges. I've had equal success with 75 eldm from a short barrel 22cm, as Inhave with a 338 rum on deer/antelope last 3 season. I killed a few critters with 108 eldm factory ammo from a slow 22" barrel last year(mv 2880) and the results were very good.
