Yeah the 6mm is pretty good for shooting LR rabbits and hares and is a good step up from a 22 cal centrefire.
If you want decent power at distance for bigger stuff 7mm is where its at, if your sexuality is questionable then 6.5mm may be more applicable.
Now in all seriousness, any of those 6mm cartridges you mention from 6-47L and bigger with a fast twist barrel so you can shoot a bullet like a 108 eld would be perfect.
Is your 243 barrel a fast enough twist to make best use of the extra capacity of AI to push heavy for cal bullets. Most factory 243s are too slow in twist rate for 100gr plus.
