It showed some promise today. At lower velocities and lower powder charges, I was getting sub-MOA. As the powder charge (and velocities) increased groups opened up. 39gr of Varget behind a 139gr SST was the most accurate, but slow... 2555fps. 40.2gr of Varget was a bit faster (2650fps) and this is where the accuracy started to go sideways. Hornady Superformance factory with 139gr SST's were 2935fps but were absolutely terrible accuracy wise. I need to find the node above 39.0gr. This gun and caliber is going to be my kryptonite. The first gun would not get anything close to sub-moa, so this one is better. I will try some heavier bullets with some differing charges to see what happens.
