What round does a Savage Arms Model 59 A use?

Answer 1

I cannot find a "Savage Model 59A" in any reference book - are you certain of the model number?

There is a common Savage rifle, the Model 99A, which was chambered for .303, .30-30, or .300 Savage. The caliber markings will be on the barrel.

If it is a .22 then it is almost always chambered for .22 Long Rifle. If it is chambered for .22 short, it will be marked as such.

If in doubt, take the gun to a local gunsmith for a professional appraisal.

The savage arms 59a is a bolt action 410 shotgun. Should have Stevens name on it above savage arms corporation.
