I want to thank you for the advice. I cleaned the barrel of my ruger before I read your reply to my last post. I now know this detail cleaning after every range visit has probably been giving me most of my problems.

I went to the range again today and at first it was printing all over the paper. Cold barrel, hot barrel, different ammo, really did not seem to matter. Then after about 15 rounds through it, I started getting tight groups. My last group was exactly 1 inch center to center at 100 yards. I was using Hornady 180 grain sp. This is my best group so far, and am very happy with it. Incidentally this group was shot with a hot barrel with no cool off period between shots. I am wondering if a cold barrel will shoot to a significantly different point of aim. This is a question I will investigate another day.

Now my question is : Should I do anything at all to the barrel? Will it be alright to just run a lightly oiled patch through it? Should I go ahead with the Hopps number 9 powder solvent and just lay off the copper solvent?
It is a stainless barrel, by the way.

Much thanks
