Really like my Tikka .223 Tactical BB, but not sure if that's legal on deer et al in all states. My go to for shoulder maladies is old M700 .243BB. There should be some on the market!Years ago I would not have ever used a 223 on deer but then HAMMERS came out and changed all that.
A friend sold me on them as he has worse back problems than me and any cartridge except 223 is out of the question.
Last year he shot his yearly doe at 75 yards and she fell on the spot.
He said since he switched to Hammer bullets they all do that.
So now I have a 223 Ruger bolt action 223 that shoots a super group with 52 gr Hammer Hunter bullets.For elk I keep my 300 win mag but if for freezer meat on deer I will gladly use my 223 Ruger rifle stoked with 52 gr Hammer Hunter bullets at 200 yards or less.
