I have a Mark II .270, bought in 1994. Not a tack driver but I bought it to hunt with. It will shoot everything I've ever tried in it, handloads and a couple factory loads, into 1-1/2 to 2 in at 100 yards in roughly the same place on the target. I did have a trigger job done on it when I bought it, it felt like a 27 lb trigger pull when I tried to shoot it in. (it was actually 7 lb.) A heck of a deer gun and it's purty.
