Is the ammo availability thing really an issue? I have a spot cut in the foam of my Pelican case for a 50 rnd handloaders box, so if my rifle gets there, my ammo gets there. This may not work for flying outside the US but other than that works great. I'm sure it's happened somewhere, but it gets brought up a lot and I always wonder if it's really that big of an issue. Kind of a tangent, I know......
And I get tired of the 6.5 Creedmoor being the end all. I own one, and it's my main hunting rifle. It's not magic. It's a easy shooting low recoil round that allows you to build good shooting skills easier than most. It's also very effective on game if used within it's proper place. I carry mine elk hunting, but I personally am going to cut my shots off at 400 or so. And that's with the 156 EOL Berger. If I lived in elk country, and hunted them every year you had better believe I would have something 30 cal with more horsepower.....
