Single shot
Muzzle loaders of the "old" style are an example. There is no action to be opened - all loading is done by "stuffing" powder, wading and projectile down the bore of the barrel.
Bolt
A model 1904 is a single shot bolt action rifle.
In a fire usually = worth nothing. You will have to replace. Donate to a museum. Never seen a rifle that was both a lever and a bolt action.
WHICH MODEL, BOLT ACTION, LEVER ACTION ,SEMI AUTO???????????
No, bolt-action only. Bummer! I was under the impression that they did some years back but discontinued the 35 cal. lever action rifle by Remington
BA
I'm not familiar with a "Winchester model 77". Is this a bolt action gun or a lever-action rifle? Winchester's famous bolt-action hunting rifle is called the Model 70. Their most famous lever-action guns are the 1873 and 1894 models. Ruger is a company that has a bolt-action rifle called the Model 77.
rifle or shotgun that cycles the bolt by means of a lever. The old cowboy guns you see on TV is an example.
Find an appraiser
They are usually broken out by the type of action- break open, bolt action, lever action, pumps, automatic, etc. AND- the muzzleloading rifle.
You do not want to try this. Find a qualifed Browning gunsmith.
Rifles have bolt actions and I've never seen a bolt action on a shotgun or handgun
