My plans to use my 'new' AR-15 during the 4 day doe season, with Barnes 70 gr. TSX, are pretty much down the drain, because I just don't have the time to get them loaded and tested. My loading/shooting/hunting plans have been disrupted by home remodeling construction, and I don't want to rush through the load development process. I want a near maximum load for this bullet, if I can find the 'sweet spot' for accuracy, and it may be touchy, due to the length of this bullet, so I am deferring this plan until I can take my time with it.
I have plenty of non-hunting ammo loaded, 64 grain steel core FMJ's that shoot 1 MOA, and 68 grain Hornady Match that easily shoot 0.5 MOA. The Hornady's are jacketed hollow points, and I'm seriously considering using them for doe season, even though Hornady makes no claim as to their suitability for hunting. My maximum range would be under 200 yards, and is most likely to be 75 -125 yards.
I would like some input from people who have taken whitetail-like game with a variety of .223 ammo. Should I only take a head or neck shot, or can I take a slam-dunk heart/lung shot. Or should I just forget the whole thing and use the .30-06 that has produced quick one shot kills every time. I have seen several one shot kills with .223 hunting ammo, but none that I know of with match ammo.
My personal assessment is that a properly placed shot in any vital area will be OK, and that I have the ability to make those shots, but I would like more opinions, since my personal .223 experience is limited.
