So my mind has gone through a number of scenarios and thought about a ton of options, and I'm actually leaning towards a .243 WIN. I can use my 6.5 CM as my primary rifle for elk (I can't help it - I'm a millennial), and the .243 can be a fun gun for my wife to shoot as well as me. We can both have a rifle for coyote hunting. I figure it can fill in even as an elk rifle in a pinch, although that would not be the main purpose.

I'm leaning towards a Tikka, but I wonder if its 1-10 twist would be limiting. The 90 grain Hornady ELD-X Precision Hunter ammo seems to be highly regarded as a hunting round, but I'm curious if there are other factory ammo choices that wouldn't work as well in a 1-10 twist barrel.
