I have an early 90's Ruger M77 Mk II push feed/claw extractor in 6mm Remington and can't bring myself to ever part with it... it shoots the 100 grain Nosler partition tight enough for any deer hunting i will do, and i am working up a load with the 95 grain BT... so my "243" is here to stay. i never had a fancy for the 243 Winchester but several buddies swear by them as a "death ray" on Virginia deer.
