Come on do you really believe those charts? Every one always out does the swift, there is a reason that it gets compared to most often when a coyote round in question. It is the long lived top end of the varmit rounds.I can tell you from a lot of field experence and reloading for just about all of them(never loaded a .204) it is very hard to put anything above it.And it is not unusual for a rounds top end bullets (grain wise) to have great b/c. I think it is a good cartidge but I will stick to my swift.
