This fall I will be going on my first elk hunt in Colorado, currently all I have hunted is mule and white tail deer. For this I have a 700 Rem .270 caliber. But am considering a .300 Win Mag. Scouring the gun shops I am finding guys trading off their .300 Win Mag for the .300
WSM. I also am looking to put on a Leupold 4.5 -14 with the Boone and Crookett Reticle. For this trip should I wait on the .300 Win mag and use my .270 with a 150 grain or will I be underpowered. I am concerned the .270 might be too light for elk. Some have said to try the .270 short mag for all deer and elk and stay with one gun. It gets a bit confusing......elk hutning isn't something I will do every year however. Also opinions on the Boone and crockett reticle would be appreciated as well.
