I am going to reply just to bump this thread up the ladder.

I am looking at two rifles & I can' t decide between the two. (they are both Cooper rifles.)
I am looking at the 6.5 x 284 & the 6mm x 284.
I am leaning real hard towards the 6.5 x 284. But then again I like the 6mm x 284. I have been looking at two Cooper' s rifle for months. I can only afford one Cooper rifle. So what should I go with?
