I have a custom 6.5-284 that shoots sub 1/2 MOA Fairly regularly but is a true 3/4moa rifle. I have 338 win mag that is basically factory with a bedding job and trigger adjustment that shoots on Avg 1 MOA. My favorite rifle is a Browning ABolt in 280 that have nothing done to it and it shoots between 1-1.5 MOA. I have several sub 1/2 moa varmint rifles.
