...FWIW, out of my 16" .308 Hanson comparing FGMM 168's & my handload w/HDY 155's & 8208 @100m during my load development.
...Yes, I like my BA tubes, use them in 300BLK, 556, 223Wylde, 6.5CM and now 6ARC. The tubes are inherently accurate, in MY experience. My handloads can easily attain sub-MOA results from them. The barrels are only 1 part of the accuracy equation, how and what it is assembled with are all contributing factors in the final result.
..with BA's MOA guarantee, you do have an avenue for replacement or refund if you aren't satisfied.
FYI, in the pic below, I didn't miss the center, I adjust my scope off a click or 2 so impacts don't obscure my aiming point...old age eye limitation, LOL
