There has never been so much ink used in discussing the proper cartridge for elk. Somehow we were "coerced" to believe that an animal twice the size of a whitetail deer needed something of greater proportion to be successful. Over ten years on this site has convinced me this has become part of our hunter DNA.
I too fell victim to this "syndrome" with magnums and calibers greater than .308 accompanying me over 22 years of elk hunting. I can now say with certainty that a proper bullet in the right place trumps proportionality. Of course, if you just want to buy another rifle, I'm all for it! Happy New Year!
