I'm going to build up another rifle for range work and maybe a competition or two if I can find any in the northeast. I have had several nice rifles from some popular builders in .223, 6.5 CM, .308 and .300 WM. Loved the 6.5 but sold it on a whim ... A mistake. I have been reading a lot about the 6 CM and am intrigued. I don't see a negative now that Copper Creek is selling ammo .... I don't reload for it yet. I have read nearly every post on the hide regarding the 6 CM and they are all very positive. Accurate, good barrel life, low recoil, easy to reload for, etc. I guess my question is, what am I missing? Is there any down side?
