Different people have different ideas as to what they want a rifle to be, they have different body shapes, and come in a wide variety of sizes. It is therefore difficult to say that gun "A" is ergonomic while gun "B" is not. My personal preference is a 6-10 pound bolt gun with a 20"-24" barrel, a 13.5" LOP, a straight stock, with enough drop at the comb to facilitate shooting with irons, but where I don't have to crane my neck to get a good sight picture through a low mounted scope. One of the great irritations of my life was picking up a Weatherby rifle, throwing it to my shoulder, and discovering that the stock fit like a glove, and that the scope's eye relief required absolutely no wiggling to correct. I hate Weatherbys, but Roy knew something about what it takes to fit a rifle to a human being.
Not surprisingly, the AR-15 has everything in the right place, and since I have recently become acquainted with one, I dare say it would be my go to rifle if it wasn't restricted . . . well okay, not for bear work.
