JohnC I just installed a Timney on my aforementioned rifle about two weeks ago...What an improvement

. I was lucky to get one from Russels, but if you can source one make sure you snap it up...you will love it.
You're groups are impressive. All I can ring out of mine so far is 3-shots a hair over an inch. Anything after three and she'll start stringing...that's an awful thin barrel. I free-floated the barrel a couple evenings ago and I am going to bed the rifle soon, I am confident she will come around to MOA.
On a positive note the rifle will put many different styles and weights of bullets within an inch and a half...not picky at all.
I think it's a shame Ruger dropped the polished stainless. I had that finish on a couple of my Rugers and I think it looks great. Deer didn't get spooked by it either...just killed by it !!!
