Our dog sport treed 2 greys in a tree on edge of meadow. I shot both out of tree, I was 8 years old. The rifle was a 69A Win. with peep rear sight. Made many pot of squirrel gravy with that old rifle. When I started building muzzleloaders I built a .32 cal. Cap lock. Many squirrels fell to that rifle. I got hold of a 32 cal. Douglas 1 1/4" across the flats. 2nd barrel had a drill wobble abut 2" from end. Had it shortened 4" and cut down to 3/4" across the flats. This was before 3/4" was made commercially. Had to make breech and finale myself.
Killed many squirrels with "Broom Handle". When age changed my eyes, Could see 3 rear sights could not hit anything. Sold it. 10/22 with heavy barrel, Laminated stock. CZ 452 Varmit, I now have a CZ 457 22LR I am tuning on for my next adventure.
