Does anyone have, or know where I can find reliable data for the 6 creedmore using light bullets. I plan on not using anything more than 70 or maybe 72 grains. The barrel is a one in fourteen twist typically use for short range bench Rest. I know that it is a great one...

Case capacity is so close to that of the .243 Winchester that starting loads for the .243 should work just fine. If you're serious about finding the optimum load for your rifle you'll have to work it up, anyway.

I've found that nothing over 70 grains shoots well in my 6mm PPC with a 1-14" twist, so you might keep that in mind.
