The first two elk that I ever killed were killed with a Winchester Model 94 30-30. No one told them what caliber I was hunting them with, so they died just as quickly. Sure, the 30-30 is low on horsepower, and there are plenty of rounds out there with more power, but it is plenty deadly guaranteed. If it doesn't die after getting shot with a 30-30, you weren't aiming in the right spot.
