Accuracy, pure and simple. They will not compete with a bolt gun day in day out in pure accuracy. Speed yes with very good accuracy normally but normally not the type of accuracy you need for a precision LR gun. Your AR platforms in 223 are the closest and they are the exception rather than the rule.
Did anybody mention that to get an autoloader to shoot like a bolt action it's going to be much more expensive? [img]/ubbthreads/images/graemlins/smile.gif[/img]
