I have a TRG-22 in 308 and absolutley love it! I love it so much, it needs a new barrel, and was thinking of going to a 6.5mm or even a 6mm. I know a 260 will work, as Europtics sells them, but was wondering if anyone has done a 6.5 Creedmoor or any of the 6mm cartridges. My concerns are that they may not feed from the magazine and that the bolt face may not work. Is there anything else I may be missing?
