I’m still shooting a variety of factory ammo to see what it likes. Hornady 147 and Winchester 140 have showed exceptional results. Hornady 140 did 0.8 MOA averaging four 5 round 100 yard groups. I want to shoot Federal 130 and a few others before doubling back.
Both barrels are Bartlein 5R’s that I chambered, ported, etc. I haven’t finalized my gas port diameter yet and am currently using an adjustable gas block. My “finalized” barrel will not utilize an adjustable gas block.
thanks for the update. I see Wilson is offering 16” 6.5C barrels (most likely what I would do). Glad to hear it worked out.
