ive heard of people using a .223. you need good shot placement and it will get the job done. I think it could take a deer down better than a.30 carbine though. i wasnt familiar with the ballistics of it so i googled it. said it had half the energy of a 30-30 winchester. i wouldnt use either really but i go with the .223. i'd try to make a heart shot or head shot.
