I'd say it's more about proper technique and simply being willing to take a little more abuse.I have one in 308 that shoots great. In fact I'd bet money that at least 90% of the poor accuracy claims are not due to anything wrong with the rifles. It simply takes a lot more skill to shoot a 5 lb rifle off a bench than it does an 8 lb rifle. A lot of people don't have those skills and won't put in the effort to develop them.
