The most questionable purchase I ever made was a M-700 BDL in .350 magnum. It was 1973, and I was 18. At the time I was pleased with this turkey. I topped it off with a 23/4X Redfield TV screen scope - my second mistake. Apparently it was very difficult to get a good seal on those things. I was brand new at handloading and my loads were not up to contemporary accuracy standards. So what I had was a very long rifle of moderate power, in a flimsy stock, topped off with a warm weather scope, which couldn't out shoot my .303.
Today I would properly bed the barrelled action it in a suitable stock, knock off 4" of barrel, mount a low power variable scope, and load some decent ammo.
