Well OP, I started elk hunting with a 1903a3 in 30-06 and 356 Winchester M94 Big Bore after my 50th birthday. After that first hunt, I bought a 340 Weatherby and shot my first bull elk with it that next season. I had a new gun and a story for it. Then I got another with it. Then I decided to lighten up, and bought a 7mm PRC a couple of years ago, and shot my third and largest bull with it (7x7). Another gun with some history for me.
Sure, the 30-06 would have been fine up to 400yds with handloads, and the 356 Win is a quick and lethal woods gun. But I just like to buy guns using the excuse of creating their own story. My next one will be a Havak Element or a custom gun in the 300 to 338 flavor. Gonna try moose.
If you want a new gun to write your new adventure story, buy one. Buy a friggin thumper. Eff it.
