I've got a 223 heavy barrel. It shoots minute of gopher at about 200 yards. Cant run hot handloads, it doesn't eject, trigger aint great, if i was gonna do it again I would buy a budget bolt gun. On the other hand, ive had it for 20 years and it always goes bang. Just mKe sure to keep it clean, and carry a ckeaning rod to eject the odd case that gets stuck.
