Please list all the markings on the gun, exactly as they are marked. Franchi did make a .22 semiauto rifle, but they are primarily a shotgun manufacturer. ACCIAIO? sales@countrygunsmith.net
Depending on condition, $300-$400. That is the listing for the CENTENNIAL model- not Bicentennial. Made in 1968 for the 100th anniversary of Franchi.
No they won't fit. If you force it, it will ruin the rifle.

Ask a gunsmith for assistance.
Depends on the exact 22 cartridge and load. Google your question and you will get lots of information.
Depends entirely on the load; can be a few hundred or a few thousand

The Slavia 622 is a .22 caliber pellet rifle not a .177 caliber rifle. It is a single shot Break barrel rifle. The rifle is a spring piston shooting system. To load and cock the barrel you simply push the barrel down (Break the barrel) all the way until you feel it cock. Load a .22 caliber pellet into the rear of the barrel (Breech) and make sure it's snug flush with the barrel. Load it with the skirt facing out and the dome in the barrel. Then bring the barrel back up into position and let it snap into place. AIM FIRE!
