I'll be honest, never really gave the 243 chance, first rifle was a model 7 and after some issues with corelokts my dad moved me up to a 270. That being said, had the 243 tuned after it sat around for years and some custom loads done with sierra gamekings. It's been heck on whitetail ever since. I rarely take it out but allow others to use it on hunts and its done well.
I picked up a used ruger m77 6mm, killed several deer with it and loved it...but I wasn't reloading at the time and ammo was hard to find so let it go. I'd like to give a 257 roberts a try and though about picking up a kimber hunter in it. I reload now so its not an issue.
Having seen recovered bullets a lot in my years I"d trust a core lokt before I'd trust a game king again. YMMV
