Mossberg Model 144

This was a popular, inexpensive target rifle in the 1960's. At the time, we never gathered data on its accuracy. (One minute of ground squirrel was all we needed to know.) Now, this rifle is back on the research bench to provide actual numbers, starting with a 50-yard target.

Notice how much difference the type of ammo makes.

We may get better results with different ammo and a higher-powered scope.
