No offense taken, Steven, but being new to this forum, I just wanted to give a bit of background on myself! I might also add that I am one stubborn s.o.g. (son of a gun) and am still fiddling with my Ruger. I may yet find out some overlooked problem. Wish me luck - - I would rather fix my Ruger than trade it!

In hot rodding, they used to say: "If it won't run fast, chrome it!" In rifles, it can be: "If it won't shoot, float it!" With modern production methods, it is very unusual to get a "bad" barrel. Many times the problem is screws not tight enough or the stock bearing against the barrel. Good luck in solving the "too big" groups with that Ruger.
