I think a "better gas seal" was desirable at the front of the chamber in the area of the cone but not at the breech area. Here is a picture of a Grade-6 T/A Parker Bros. hammer gun I photographed extensively for an article I have been working on. It is obvious that relieving the gas pressure at the breech faces was the desired result of this machining. . |

I have shot mine several times with modern shells. I do not have any brass shells.
I have never noticed any deformity, dragging, hard to open, etc. The guns functions great. I did not have to do anything to the head space to make modern (RST) shells fit. They went right in. I am not really sure what function this feature provides. |

I have seen this feature on the Darne guns before, but in those the barrels slide forward to clear the shell from the standing breech.
Gary, upon opening the gun you pictured after firing a shell, does the cartridge base drag against the recess such that the gun is hard to open? Was this recess in the standing breech only in some lifter actioned Parkers. or did some top action hammer Parkers also have it? I've never seen it in any hammerless Parker and assume no one else has either? Did some T-latch Parkers have it? The ones I have seen did not. |

Dean I have seen that done in the event of a peirced primer usually on rifles. That is the first shotgun I have seen with this feature. I believe that what we are seeing with these rebated guns was an attempt at what was precived to be a better idea. Perhaps they decided it wasn't needed any longer.

Bruce no the shell does not drag or is it hard to open ,again as John points out this is with modern shells not brass and it is a 10 gauge. Gary
