I would scope it with a vintage scope to determine its full accuracy potential. A scope is a great advantage squirrel hunting and especially if you have older eyes.
The most accurate Winchester bolt-action, and best quality, was the model 52. Even the Browning/Winchester 52 sporter reproductions were excellent. My Browning 52 sporter is on the level of quality close to my 54-action Anschutz. The 52 sporter will group in the low 0.3’s with the HP’s it likes.
