22 rim fire rifles are not good to dry fire, some can be damaged which one s are ok to dry fire
It is generally not recommended to dry fire 22 rimfire rifles because the firing pin can hit the edge of the chamber and cause damage to the gun. However, some modern 22 rifles are designed to handle dry firing without any problems, such as the Ruger 10/22 and the CZ 452/455.

If you are unsure whether your rifle can be dry fired or not, it is best to consult the manufacturer's recommendations or to use snap caps, which are dummy rounds designed for dry firing practice. Snap caps can help protect the firing pin from damage and allow you to safely practice your trigger pull and other shooting techniques.

why are these ok, it because they are based on a Mauser action
The reason why some modern 22 rimfire rifles can be safely dry fired is not necessarily because they are based on a Mauser action, but rather due to their design and construction.

For example, many modern rimfire rifles have firing pins that are made from durable materials, such as hardened steel or titanium, and they are designed to withstand the impact of dry firing without causing any damage to the rifle. In addition, some rifles have breech faces that are made from tough materials, such as stainless steel or aluminum alloy, which can also withstand the impact of dry firing.

However, it is important to note that not all modern rimfire rifles are designed for dry firing, and it is always best to consult the manufacturer's recommendations before attempting to dry fire any firearm. Using snap caps or other dummy rounds designed for dry firing practice is also a good way to practice your trigger pull and other shooting techniques, without risking damage to your rifle.
