Having all 3 (well, my 243 LBC might as well be a 6 arc), stick with the .223, especially in this environment and especially if you don't reload. At least you can find ammo and/or components (aside from primers). If you must go beyond that and a coyote is the biggest thing you plan on shooting, go 6 arc. Better ballistics, flatter trajectory at coyote ranges and notably less recoil. My 18" 243 outshoots my 22" Grendel and it's recoil is right in the middle of 223 and the grendel. 70s are probably as light as you want to get in ARC, though. Anything lighter may go bang, but jump will be either too long or the bullet won't be deep enough in the neck. I got the 70 gr NBTVs going 3060 out of my 18" with XBR. Stopped that project, but may go back to it now that I've scored some Benchmark, which will likely excel.
Let's go Brandon!
