Leatherman, since you say for hunting and plinking, especially deer hunting, something we hold sacred here in Texas. I'd go for a quality AR, DPMS, RRA, COLT, OLYMPIC ARMS, BUSHMASTER, with a 24" barrel for the extra velocity, flat top reciever so you can mount good optics and although the rifle does not kick much to begin with, it is less with a longer, heavier barrel. I'd go with a 1 in 9 twist so you can use the Barnes x bullets in 55 grn. But as new bullets come around you can use up to 70 grn bullets, but you need a high quality bullet to humanely shoot something of that size and expect it to penetrate and expand without losing weight. I killed my biggest deer, a honest 151 Boone and Crockett, with a .223, not an ar15, but a 24" CZ527 bolt rifle, I did not intend to do this, as I was actually looking for turkey, during deer season, but I loaded the Barnes X bullets just in case, well just in case happened. The shot was 80 yards, and I said if I do this, shoot for the neck, and I did. He dropped on the spot, bullet did not exit. For what your initial criteria said, I think this would work well for you, rifle for 700 bucks down here, and that leaves you 300 bucks for optics. If you already have the glass, you might splurge for a national match trigger and have a few bucks left over.
