Make sure the gun is unloaded. Raise the bolt, then squeeze the trigger while pulling the bolt to the rear. I've never seen a bolt action where this didn't work.

Standard 16 gauge shotgun shells.
1930's-40's.
remington wingmaster 16 gauge
No age records, most likely a Mossberg shotgun, values $50-$75.
it is not safe to fire 16 gauge shell in anything but a 16 gauge.No shells will interchange with other gauge guns since a 16 gauge shell would fit in a 12 gauge chamber, I would think you can do this.
