RE: Opinion on the 223 as a deer hunting cal ?
IMO if you can take short range shots it will work.(100 yards or less)I know someone on here is going to tell me they killed one @ 500 yards,thats great but I hunt for large Mo mature bucks.They weigh 200 +lbs.I will use my .300wm,45/70,.270wsm or my 6.5X284.Some are over kill but very effective.
