The Swede is pure class all the way. Very few cartridges are half as sexy, nostalgic or effective as the 6.5 Swede. Fewer still are as available. Perfect 10's are exceedingly rare. The 6.5 Swede, the 7mm Mauser, the .38Spl and the 22 rimfire are all perfect 10's. All are a century old, all are more effective than their paper ballistics would have them be, and can be comfortably handled by experts and rank novices. Also, they are all hugely versatile.
I own three Swedes at the moment. I own other 6.5 cartridges and like them a lot, but the Swede is the one that I loan to a first year deer hunter. I honestly believe that the only cartridge that rivals the Swede as a perfect deer killer is the .257 Roberts. The "Bob" is a 9.9 as it is less than a century old, originated as a wildcat, and is not quite as versatile.
Having said all of that, I don't like the 6.5 varmint bullets for coyotes. In my experience, those bullets under 100 grains and designed for varmints would be perfect for 'chucks or smaller critters, but if you are into saving pelts, the light bullets are [beeep] on fur. I have never done so, but I can envision the Swede turning a woodchuck into a very colorful rorschak test blot. I have had good experience with standard cup and core deer bullets of 120 and 140 grains on 'yotes.
