Somewhat of a shameless plug here, but this is a good option that can really breath new life into that 6.5-284. The 123gr Flatline has a better BC than the 140 class bullets and can be driven at 3300fps without pressure signs. Thus, retained velocity at target is much higher, TOF is significantly reduced, so elevation and wind call adjustments are significantly less. Supersonic to 1800 yards at sea level. And you can't over spin it; nothing to come apart since it is a solid.
