Re: 221 fireball
I have a CZ 527 in .221 Fireball and really like its looks, ballance and accuracy.
It has a factory single-set trigger, factory supplied scope rings, 5-shot removable box magazine, hammer-forged 22-inch barrel and is very, very accurate.
The test target that came with my rifle shows 3 shots into 0.375 inches at 100 meters. Not bad!
With the new Remington factory ammo (50grain V-max), I have been getting 0.75 inch groups from shooting sticks and seated position at 100 yards--plenty good for coyote.
The Fireball is also very "quiet", as compared to a .223 Remington. Actually, the ballistics for the 50 grain bullet in the 22-inch barrel (.221 Fireball) are better than the .223 Remington in a 16" carbine. Quieter, too.
The Fireball is worth a look if you want a highly efficient cartridge for 200 yard coyotes or 400 yard PDs.
I would go with a Nosler 60-grain Partition or the Barnes XLC 45-grain bullet for larger critters (and keep range short with perfect shot placement).
