Dry Fireing

[stokesrj]

Rimfires also should not be dry fired, since the firing pin hits halfway on the breech, creating uneven wear on the pin, and resulting FTFire in the future.

It is true that some rimfires should not be dryfired. But it is no trouble for some designs. Anshutz match rifles can be dryfired hundreds of thousands of times without damage. They are designed to take it because most serious small bore competitors dryfire more than they live fire. Other rim fires will receive such a peening on the edge of the chamber that it will prevent rounds from being chambered. The key is that the design limits the travel of the firing pin so that it does not contact the chamber edge.

The AR is pretty much immune to dry fire damage other than wearing out the springs more quickly. The AMU requires their shooters to dryfire drill over and over. There is a device that can be inserted into the bolt carrier to absorb shock and make it easier to cock, and reduce the db level of the hammer strike, but hardly anyone I know uses them.
