I want a rifle that would work well for both deer and elk. My brother and I were considering the Remington 700 young buck (because of the shorter stock) .243 but then my husband brought home a Remington model 700 tactical 6.8mm. After reading some I am thinking that the 6.8mm is going to be too small a round for elk. I need opinions because as you can tell I am a newbie. No debating please. ETA: I am more than willing to hear about other options.. Thanks!
