Winchester Model 62 Pump Action Rifles The ultimate gallery gun
Several models of Winchester 62 pump action rifles. Top to bottom: 1906, 20-inch round barrel; 1890 octagonal barrel; prewar M62 with scope; postwar M62A.

No less than six generations of the Model 62 were made from 1932 until 1958. Three of these are pre-WWII while the other three are post-1945. The easiest way to tell postwar versions is that they have a 17-groove 8.75-inch foregrip while prewar versions have a 5.75-inch 10-groove grip. After 1940, the Model was modified with an improved hammer spring and dubbed the 62A, so if you see a 62A mark on your Winchester pump rifle, that is an easy way to tell that it was made after that year. The value of standard Model 62/62As start at about $300 for shooter grade guns and go as high as $1000.

Yes you can but you didn't include any model info, just that it's a Rossi brand.

Shotguns are at the bottom of the list.

I'm having trouble visualizing which pin (firing pin???) you're talking about. How sure are you that the rifle has been reassembled correctly? Could you post a picture so we can see how it's assembled? One shot (no pun) of the assembled trigger group would be good, then another shot of the bolt & carrier.

Bullet proof vests normally provide very little to no protection at all against bullets fired from rifles (like the M4 carbine 5.56mm or AK-47 7.62mm). They only provide protection against bullets fired from all hand guns.

have you checked your ammo by firing it in another weapon?

Model 61, 62a, the 61 is hammerless and the 62a has a hammer, the safety on the 62 is the hammer, the safety on the 61 is a cross bolt, sounds like it is gummed up, or busted, I would take out the trigger houseing and clean it up and check it out. If the cross bolt is stuck, something is blocking it, like the hammer at half c0ck, try pushing the trigger forward and see if it moves, whatever happens, I would still take it apart and clean it, don't screw it up, it is a very collectable rifle.
