Increasing my rifle battery
Hello all, I've been more of a handgunner and just recently got into big game hunting. I live in Colorado so Mule Deer and Elk are the usual suspects. Recently I noticed some Weatherby Vanguards on sale for a good price. Currently, my only centerfire rifle is a Marlin 336 in 30-30. Its a handy good shooting rifle but would like something more powerful for longer ranges and Elk.
I saw a good deal on the Vanguard in 270, 30-06 and 300 Wby Mag. I'm torn between them. What would you choose to complement my 30-30 rifle for Rocky Mountain hunting or as a general purpose hunting rifle? I reload so I could get the most out of any of those choices. I've heard that reloading Weatherby cases can be tricky.
