Saying Rugers are innacurate is like saying savages are Always more accurate...they are devices made by machines...there will always be outliers on both ends that escape the assembly line
That said, every ruger i have owned (5 m77s and a No.1) have been quite accurate. Judging a sporter weight bolt gun by five shot groups is an un fair test (needlessly over heating the barrel)...the true test of a hunting rifle is can it consistently place a single, one, uno, 1 bullet from a cold bore at any given time, exactly where i want it. Single hole groups are less interesting to me than single shots dead nuts in the right spot. Thats something my Rugers excell at
