Hi, just stumbled across this forum while I was doing some research for a upcoming 6.8 build. Have been reading through allot fo information and I can see this will be a great site for all sorts of technical information regarding the 6.8 cartridge. I'm partially holding out on buying my 6.8 upper to see what might be on the horizon as far as piston driven systems. Also anxiously awaiting this "cheap" SSA plinking ammo.
