[QUOTE="Bart B, post: 1148017, member: 5302"] One of the best comments on in this thread. Accuracy doesn't fall off the SG cliff when the number goes below 1.5. That point was picked as the limit of accuracy degradation that's on a gradual downward slope based on the developers objectives, standards and conditions. Someone else may have picked 1.6 or even 1.4. I doubt anyone could see a difference in long range accuracy with any bullet and velocity whose SG went from 1.55 down to 1.45. They may if they shot the load from a machine rested rifle inside a building with perfectly stable atmospheric conditions and shot at least 20 shots per test group and both were well under 1 MOA. And the OP will shoot 180-gr. bullets more precisely than heavier ones which typically masks a small loss of accuracy due to its lower BC. Picking the right powder and charge weight coupled with a good primer (Tulammo LR) and the muzzle velocity spread will also drop increasing accuracy. [/QUOTE]
