.223 will work, but hittem in the brain pan or neck, else-wise you'll be tracking for a week.
maybe, maybe not...but not a .223 rifle shooting 5.56 NATO ammo. That is an unsafe combination.223 will do the job.
Sorry castnblast until dedicated varmint models started being offered most .223 rifles had a 1:9 twist or faster. Most guys using a .223 bolt action rifle in this caliber will have a slower twist or a dedicated varmint upper for the AR. My DPMS M4 carbine has a 1:7 twist and my H&R Ultra rifle has a 1:9 so I don't have any problems stabilizing heavier bullets. The whole .223 cartridge was designed around using heavier grain bullets, 62 grains being the norm not the 40-55 grain varmint bullets.Most 223 rounds are made for vermin...Also, due to this fact, most 223's have a 1:12 or 1:14. Those won't stabalize a heavier bullet.
