The model 311 was made from 1941 to 1989, but since you have a serial number I would guess yours was made after the Gun Control Act of 1968. You could probably find out by contacting Savage Arms at the related link posted on the right side of this page.
Yes, wasp and hornet sprays will also kill bumblebees. You can find wasp and hornet spray at retail stores such as Walmart or Target.
