RE: Smallest Caliber For Deer Hunting
Even though this thread died rather fast I will still chime in with my thoughts.
Traditionally most smaller caliber rounds were labeled varmintroundsso they were loaded with very frangible (explode on impact) bullets which aren't suited for deer. Over the past few years the bullet manufacturers have started loading a lot more factory ammo with good quality solid bullets in small clibers such as the .223. A 62gr BARNES X bullet loaded in .223rem will take out any deer in the United States if the shooter does his job.
