There is no rule against using lowe BC bullets in 6mm CM either.

Like I said, I'm young (not even 40 yet!), so I'm still learning. I think I always thought of the Creedmoors as being made for lower velocity, high BC bullets. They have the faster twist rates and, in my limited understanding, could over-stabilize the shorty, more explosive varmint bullets. I've killed so many groundhogs with 50 or 55 grain vmax, it seems dissonant to shoot a 58 gr or 75 grain bullets out of a 1:7.7" barrel. When I would think in terms of large game hunting, the 6CM made the most sense. But on an annual basis, I may shoot 20 - 50 groundhogs, and only 2-5 deer. So for "one gun does it all," the 243 won out.
In retrospect though, I was wrong. 6mm target bullets would be just fine for groundhogs. I'll just try to use all the 243 brass I already have to comfort myself for now. Haha
