funny thing about all the Ruger bashing,I've owned 3 of them,a Mini-14,a M77MKII and a SP101,they all were accurate as I think they should be.
The Mini was the closest to be a disappointment,it made 2-3" groups at 100yd...that was a problem if you were going to try and kill a thundering herd of coyotes,the first shot was always right on,I shot at exactly one coyote with it,170yds (rangefinder) and I dropped her on the spot,if I'd have missed I'd have had to let her go.
The markII shoots about MOA with federal 140grain,and I think it's a pretty rifle to look at.
The SP101 was the stubby in .357mag,and shot great,I never measured the groups,but they were better than I expected with that short barrel.
The best rifle as far as accuracy I ever had was a Mod70 "black shadow" .270, a ugly and poorly constructed rifle if I ever saw one,but that thing would make a group that you could not tell for sure how many rounds were fired,around .5 across,with a 4x weaver scope on it,but I kept the Ruger...
Really,if you want a tack driver it would be best to avoid Ruger,but I gotta say I've never really understood all the bashing,the Mini is not really as good as it should be,but if it were then I don't know why anyone would bother paying for a AR.
(As Mr.Wilson said,unforgivably small sample size,but I shoot everything I can get my hands on)
