I think the 6.8 spc is a great choice for what you want. Of even the 6.5 grendal or 264 LBC. There is also the 30rem ar you should look at and google 30AAC blackout read that.
Look at SSK industries they have alot of custom options as well.
I have a LMT MRP CQB I can change from 5.56,204 ruger, and 6.8 spc in about 2 min by swaping barrels. That might be something to consider for you as well.
Sorry, But I have to disagree with all of your choices just as you disagreed with mine.
If you want to spend all of your time tracking then it's ok . Or make all of your shots Neck shots
so they will fall where they were shot.
I happen to like the 223 but like all cartriges it has it's place and big game is not it. In any case,
I would not recomend any thing lighter than a 22/250 for deer with a clear conscious.
The reason I recomended the WSSMs was they are the most available and very powerful in
an AR platform and can be used at extended ranges.
Of all the cartriges I could find these are the energies listed=
204 Ruger=1357 ft/lbs
223 Rem =1282 ft/lbs
223WSSM= 1810 ft/lbs
243 WSSM=2258 ft/lbs
25 WSSM =2347 ft/lbs
6.5 Grendel=1875 ft/lbs
6.8 SPC =1588 ft/lbs
The next ones are short range (300 yards max).
458 Socom = 335 grain @ 1800 ft/sec for 2405 ft/lbs of energy.
450 Bushmaster = 250 grain @ 2200 ft/sec for 2686 ft/lbs of energy.
50 Beowulf =334 grain @ 1900 ft/sec for 2678 ft/lbs of energy.
The "recomended" impact energy for one shot kills on deer is 1000 ft/lbs of energy, so if you
subscribe to these energies some of the cartriges have less than a 100 yard effective range.
So you be the judge as to what you will be willing to live with.
