If I read right you said you wanted a 6mm for rockchucks, paper, and maybe in the future an "occasional" antelope. My thoughts were mostly based on that comment.
With your planned use in mind the 6x47 gives me great accuracy, efficiency, barrel-life, and won't wear me out after a day of shooting varmints. (granted the 6AI doesn't have TONS of recoil but the 6x47 still wins with less)
I haven't tried anything heavier than 95 gr SMK's in the 6x47. With 39 gr of H4350 they go 3100 fps and are really accurate. The 6AI will of course shoot bigger bullets faster (my 6AI shoots 107 gr SMKs @ 3300 if I remember right) but at the expense of recoil, more powder usage, and probably less barrel life.
The 6x47 still has enough "umph" to hit the occasional antelope hard enough to get him down at range. If your planned uses were reversed (if you wanted a 6mm deer/antelope gun that would "occasionally" see paper/varmints) then I would say the 6AI would win out.
I hope that all came out clear... Keep in mind I'm only comparing the 6AI and the 6x47 for your application, which is similar to my situation actually.
Being a younger shooter I have not yet had experience with 6BR's, 6XC's or 6-06's so my expertise is limited there. So you may find other info from those cartridges that better fits your bill.
Hope this all helps
