The AR workt great before the shoulder problems but after I find it way too uncomfortable to use unless its on a bench. For me anything bigger than 243 is limited to heavy guns and low round counts. I used a 6.5-284 for antelope and deer this year with good results but the gun weighs 13# or a little more and I USED the bipods!
Last year I used a lite little 6.5x55 Sweede off the bipods with a good recoil pad with ease but I sure wouldnt want more than that!
My favorite critter-getters are my little Stevens in 204 and the CZ American in 223. The recoil and lite weight make them an easy choice for carreing around and shooting offhand. With a good rest both are coyote units to 400 yards or more if the wind aint blowing too hard.
