Your Winchester model 25 rifle will take any size scope that you see fit to use as long as the rifle is drilled and tapped for scope use.If your rifle comes with a 3/8in.milled receiver rail then you must use that size scope ring bases.I recommend that a good 4X power scope is all that is needed for the effective range of .22cal rimfire ammo.
For a Bushnell Buckhorn 3-9x40 rifle scope, you'll typically need a scope cover that fits a 40mm objective lens. Look for a cover labeled for 40mm scopes, which should provide a snug fit. Brands like Butler Creek or Vortex offer universal scope covers that can accommodate this size. Always check the product specifications to ensure compatibility.
The Winchester Model 250 typically uses a 1-inch scope tube, and it generally requires a scope mount that fits standard 1-inch rings.
