It is in the Winter Issue James - and Thank You Very Much for your contribution.

Yes James! There is that also. You can see that difference when you drop a rim recess reamer like I have from Clymer into the bore. The cutters do not hit evenly on the recess because the chamber end of the barrels is not 90deg to the bore axis. Because of that I have not tried to ream my DH12 recesses. I was/am also very reluctant to modify the recesses just to fit poorly made shells.

Has anyone compared the current recess dimensional standards to that of yesteryear? And, Richard, your comment about the reamer seems to suggest you would be increasing the diameter since the bottom of the recess should be 90 degrees to the bore.

I had no way of determining what if anything was off but suspected that the reamer was not made properly. Nicely made old paper shells drop right in and the rims fit just fine if the shells are put in backwards to compare the rim with the recess. All I could see was that the reamer was not hitting the recess evenly and I was not about to experiment. I just don't shoot AA hulls in the gun, ever. My 28ga Repro does the exact same thing with AA hulls and sticks shut even harder than the DH12. I've had to put the Repro in the vise more than once to get it open.

aint it a shame that everything made a 100 years ago is better than nrw things...mabe man is going backwards instead of forwards ...charlie

The gun is now in the hands of a highly respected gunsmith. In his opinion there was something (probably a piece of shot) down in the action which eventually moved. There can be no other explanation.

I wonder how a shot pellet could have gained entry to a Parker's innards.....

And even if a shot pellet were inside, can't envision how it could block lever movement.

Though it could be possible. Especially with reloads and bad crimps... I think the statement of "maybe a piece of shot getting in there" is a lot like "maybe it needs to be cleaned". A general statement made not knowing the actual cause of the issue.
