True. Those numbers based on all 20" barrels...which is what I will be building. All the reading I have done show similar results with the longer ranges. Many folks DO need something out to 600yds and beyond. Evidently, the 6.5G holds it's energy better largely because of the way the actual bullet is shaped/proportioned. Like I said...this is all new to me except for the research. Probably Big Al, or someone who currently PLAYS with the 6.5G, could explain further.
