RE: A good coyote gun for not a lot of $$$$$
Buck...the 223 is accurate to 200 yards. Shooting 55 grain V-Max bullets from Remington and sighted in at 100 yards, the bullet hits 2.5" low at 200 and 10" low at 300.
NEF used to make a 250, but I don't know if they still do. The 22-250 is one whale of a caliber. Sighted in at 100 yards, the 250 is only 8" low at 300, and still smoking.
