CZ 527 Ultralight Predator
This is my coyote rifle. It is a CZ 527 M1 Ultralight Camo Predator, chambered in .223 Remington. It is lightweight, fully camouflaged, and in an ideal caliber for hunting coyote. It has a single set trigger. After some initial load development, this CZ is beginning to look like a ½ MOA rifle.

Optics
I have topped this with a Nikon Coyote Special 4.5-14x40mm Predator BDC Mossy Oak Brush Camo scope. BDC reticle (drop marks and "open circle design doesn't obscure target, making shots on a moving coyote simple"). Anti-Reflectice Device. Side focus parallax adjustment.
CZ recommends 65 in-lbs for the scope ring clamping screws. I will assume the standard 18-20 in-lbs for the ring screws.
The BDC reticle has positions for 100, 200, 300, and 400 yards for a .223 Remington with a 55 grain bullet. The actual ranges should be calculated once I know the ballistics of the hunting load I will develop.
Reticle Point | Drop @100yd |
MOA | Coyote Load |
---|---|---|---|
Center Circle | 0" | 0.00 | 100 |
Bottom of Center Circle | 1.5" | 1.43 | 210 |
Second Circle | 3" | 2.86 | 280 |
Third Circle | 5.5" | 5.25 | 375 |
Ammunition
The purpose for owning this rifle is to take coyote. I wanted to develop an accurate handload capable of long-range performance (up to 400 yards) using a varmint bullet with a high ballistic coefficient. I succeeded with a load based on the 53 gr. Hornady V-Max, which yields ½ MOA groups.
Zero
This rifle is currently zeroed at 100 yards for the 53gr Hornady V-Max with 25.8 grains of IMR 8208 XBR, Federal 205M primer, Nosler brass, a COAL of 2.260" and no crimp.
