X-Caliber barrels on Savage and Howa Mini

[6ARC904]

I have a 6 ARC built by Kenny and it does exactly what he said it would. 5 shot group 1/2 MOA or better at 100 yards. I have the 26.5" X-caliber barrel with the MTU contour with a 1-7.5 twist rate. So far my best 5 shot group is .416' at 100 yards with Hornady Black 105's.
