This is spot on. I would say that "varmint loads" are only appropriate for older, big game cartridges that don't have the modern ballistic performance of the 6.5 CM. In those older cartridges, the reason for going with a lighter bullet was to gain velocity and get a flatter trajectory, maybe out to 300 or 400 yds. It might do a little less pelt damage, but that depends on so many other things that can't be controlled. The whole point of the 6.5 CM is to use a much better bullet and cartridge that isn't so dependent on speed. For coyotes, I use the same Hornady 143gr ELD-X or Nosler 140 gr RDF that I use for hunting (deer and up) or shooting matches. One huge advantage a 6.5 CM can give you over other favored varmint cartridges or loads (think 22-250 Rem or a 90 gr 270 Win) is the capability to threaten smart coyotes out in the 500-600 yard range and beyond. I've been on many a stand with my 4000 fps, 50gr, 22-250 Rem and the coyotes hang up at 600 yards. Can't touch them with that light, fast, bullet set up. Different story with a 6.5 CM and the 140gr it's meant to shoot.
