Did a tall target test and had an error of about 1.5%, accounting for that, G1 BC of 0.27 matches my drop at 300m. about the same as flat nose 30/30 of the same weight. https://www.sierrabullets.com/store/...0-30-170-gr-FN a bit less than advertised 0.630. holes a little bit oval shape out of 1/7in twist. Group was 1.8MOA (3 shots)
