Coned breaches on repeaters

[Grantmac]

Anyone used a coned breach on a repeater? I'm looking at fitting a new barrel which will require extensive reworking of the extractor slots, would be easy to cone on the lathe.

Should have no affect on function

A cone breech has the advantage of having no extractor cuts to line up. Depending on how the barrel is attached to the receiver, a cone breech also has the additional potential advantage of allowing the barrel to be indexed.

Below is an example of a cone breech. It will be obvious that such a breech can be relatively easily damaged, especially if dry firing results in the firing pin striking the breech in any way.

A hybrid cone breech with very wide extractor cuts may be preferable.

A coned breech is the cheap and easy way out. A flat breech with extractor cuts takes more work but it is much sturdier. I have done both at customers requests but personally would not want a coned breech... it is much weaker and easily damaged.
