I'd like to know how far a good .223 bedded with pillars and good factory ammo can make a clean kill on varmints. This question is besides shooter skill. I've been thinking of getting a CZ 527 Varmint in .223 with a Bushnell Elite 4200 Tactical scope, But need to know if this caliber is okay and it's max efficient range. I initially wanted the 22-250, but that's changed. This would be for small game varying in sizes between rabbit and fox.
