I don't think 6.5G has anywhere near the market support that 6.8SPC or 300BLK has, not to mention ammo availability. Sure you can find the stuff, but options are much more limited than they are with the two other options. Given 6.5G's high BC it is a shame, but also a reality.
Anyone have any experience with the 6.8 through a 12.5" barrel?
