You have to remove the barrel. Take the stock off and you will see the nut that holds a "U" clip in place. The clipp holds the barrell. Remove clip, slide barrel out, then the bolt will also slide out.
Assuming you mean the Stevens Model 238 bolt-action, I have magazines. sales@countrygunsmith.net

"this is a lever actun not a bolt" Incorrect. The Stevens Model 58C 410 Shotgun is a bolt action. I think that the store at the following link has magazines in stock: http://www.gunpartscorp.com/Manufacturers/SavageStevensSpringfieldFox-33479/Shotguns-40503/58Series-41363/58C-34126.htm?page=2
Open the bolt, ensure the chamber is clear, then insert rounds into the magazine through the bolt opening (this may be done loading each round by hand or by inserting a stripper clip into the guides, then pushing down to push the rounds off the stripper clip into the magazine).
