Zchaparal;
You didn't list where you are.
Deer in Florida and S. Texas are a different "critter" than those in the upper mid-west.
The deer in Florida and other parts of the south may run to not much over 150lbs (if that big!). Whereas deer in the upper mid-west can easily top 300lbs for a mature buck.
I've shot over 200 deer in the last 30yrs with the .22Hornet, .223, and .22-250. However, the were mostly does taken during culling operations.
If you don't reload and your deer don't run over 200lbs, the .223 with most any SOFT POINT load 55gr or heavier will do fine. No need for uber-expensive ultra-premium bullets which may not perform any differently than a FMJ.
If you are in Iowa, Indiana, Kansas or such where the deer can get very large, then the reduced recoil or as Remington calls them "Managed" recoil loads are a better choice.
I've killed a lot of deer with the 7.62x39 using 125gr Sierra's as well as 125gr Nosler Ballistic Tips, as well as 130gr Speer HP' and FP's.
At reduced .30/06 load velocities they do very well.
The Remington 125gr CorLokt Managed recoil load has an enviable reputation in my area.
All three of a friends daughters took their first deer with a T/C Contender Carbine in .223. All have been one-shot kills. However, the girls had shot the gun a LOT and I was loading him Hornady 55gr SoftPoint over 27.0gr of BL-C2 for around 3,000fps from the "Carbine".
I personally prefer the 63gr Sierra SemiPtd Spt and 65gr Sierra GameKing. A close third is the 60gr Hornady PtSpt. These all are strongly constructed bullets and I've never seen one break-up and fail to penetrate.
Shot placement, shot placement, shot placement....
