order of my vote for caliber preference: 6.5 SAUM or PRC 6MM creedmoor 338 Federal
but I would probably buy the 280 AI if made and that was the LTD edition
I'd be willing to bet that 6mm CM would be a very popular choice, and I can only imagine how sweet a 338 federal would be.
Of course they will never make the 6.5 SAUM or PRC, but worth noting that when you ask rifle loonies what they want- the 6.5 SAUM always gets a share of the votes.
