Once upon a time I had a Ruger No. 1-V in .223 Remington w/ a 6.5-20 40mm Leupold on top. It shot O.K. with various 55gr. loads. It tended to string shots vertically. One day I shimmed the forearm with the result that stringing was eliminated. Then one day I loaded some Speer 52 gr. hollow point bullets over a nice modest charge of BL-C2. I was shocked. Not five but ten shot groups fired in the scalding hot summer of south Ga. yielded groups of .50 MOA. The barrel would get so hot that I'd lay newspaper over the barrel so that the heat waves coming off the barrel would not affect sighting through the scope. Foolishly I let it go as I simply had no where to shoot the rifle beyond 100 yds. It was a beautiful thing. At that time Ruger really was putting beautiful wood on their rifles, and the single-shots seemed to be stocked in remarkable pieces of walnut.
