Like the title says, what is considered marginal for elk? The reason I ask, is I think most people say the minimum is 27 caliber. I have a nice m77 chambered in 260 Remington that I absolutely love! I was thinking with a good 140 grain bullet, say something like Barnes Triple Shock, it would be plenty for elk out to 350 yards. What say ye? I also have a 35 Remington, but that would be seriously limited by range.
