I do enjoy that .243 was around FOREVER... then competition people moved to 30cal, then 7mm, then 6.5, and now back to 6mm.
High velocity 6mm is better than all those stinking mid velocity overpraised 6.5mm.
Necked down 6.5 cartridges to 6mm have better performance~ Also as a side effect the Ogive is longer in comperasion to the caliber (form factor), without exeeding OAL of the cartridge and action.
