Coned breaches for .22 rimfires

[Keith23]

I see many advantages but could someone tell me the down side to coned breaches for .22 rimfires???

A dry fire is far more likely to ding up the chamber.

Empty case

Always keep an empty case in the chamber if you plan on leaving the bolt in.

As previously mentioned... the edge of the chamber is considerably weaker and easily damaged...

and it does not look as nice as correctly cut extractor recesses...
