Middle 300-ish bullet weight range, slowed down, does wonders on elk. Just like with a centerfire, you don't need to be cranking up near the redline to kill an elk. My bull last year fell just fine to 95gr BH209 and a Hornady GP 385. Load shoots great in the TC Encore. In the Triumph its a bit heavy on recoil, same with the new Federal Trophy 350.
