The .204 will shoot flat and far just as well as a .223,thats what I have been using for Coyote Hunting....a CZ model 527 .204 in the "Varmint" and it is easy on the Hides and will flat knock a Coyote down.I started out with 32 grain Winchesters and changed over to the Federal loaded V-shok 39 grain Sierra Blitz Kings!
I also have a Savage Axis in a .223 shooting 55 grain V-max Hornady shells,that does well in heavier cover or windy days!
If You shop around You can find most Ammo cheaper at different Ammo Suppliers,the part where they get You is the darn cost of shipping where they stick it to You!
I also prefer Hornady Ammo ,Remington or Federal to shoot in my Rifles!Oh yeah....a 32 grain bullet will travel at around 4,000 FPS in the .204 and around 3,650 FPS using 40 grain ammo....thats fast!
