You may recall the Winchester Model 72 I bought a few weeks ago from A Boy And His Rifle Part V. I finally got the time to set down at the bench with some match ammo this weekend. Above you can see the 10 shot groups all fired from a bench rest at 50 yards. If did not like the sub sonic ammo.
The peep sights on the 72 are great for shooting but not great for adjusting it to zero. Its not a precise method at all and I still need to tweak it. Like all of these old .22s it is a very good shooter. My advice is to always buy a vintage Winchester or Remington rimfire rifle if you have the chance.
