I owned one for about 7 months in .270, it shot very well, and was a good rifle, I sold it to a family member, though. I wish i had it backI was at their website, last night after I read a good article about the ATR 100. It said, 270, 30-06, 308, and 243. That's all it said. For 262.00 plus tax out the door at Walmart, it sounds like a good deal. If I can just find one who still sells them.
