I would like to get a Centerfire Squirrel Hunting Rifle. For years .22 Short and .22LR have done me well but I want to use a Centerfire cartridge. I have a few candidates and was wondering which would be best. A local gun shop has a few rifles in .25-20 WCF they are a Savage Sporter , Remington Model 25 and a Savage 219. My friend has a Martini Cadet in .32-20WCF that he no longer wants and has 100 pcs of empty brass and 40rnds of 100gr Winchester factory ammo. I have a Martini Cadet in .357 Magnum that I was thinking about loading with .38 Short Colt and a low grain bullet. Another gunshop local to me also has a Martini Cadet in .17 Remington but there isn't a price listed for it yet in their shop, the barrel has no sights either and would either need to be drilled and tapped for a Scope or have dovetails cut for sights. If anyone wants to throw in their two cents by all means do. Most I have thought up so far was the whole .38 Short Colt for Squirrels. If anyone has better caliber suggestions please share them. Personally I like Single Shot rifles but I dont mind repeating rifles as long as the are manually actuated. I dont like Semi- Automatics they're not my forte.
