Lot's of crazy information floating around this thread about the .204 and Coyotes. 30gr bullets? 400 yards?
Look the .204 is basically a varmint gun. Low recoil, little less noise and flat trajectory make it so it excels sitting over a prairie dog town. It's also perfectly acceptable for coyotes and other predators. But the 30-32 gr varmint bullets are too light in construction and the little pills run outta thump pretty fast. Best to stick with the 35-40 gr bullets (Bergers) and shots out to 250 yards. If you need to shoot coyotes beyond that range you're into .22-250 and .243 territory.
