Maximum Chamber Pressure -- Parker Reproductions

[Victor Wasylyna]

I am curious what those shooting Parker Reproductions, particularly 12 gauge Parker Reproductions, consider as a maximum safe chamber pressure. Are you comfortable shooting loads that generate 10,000 psi? 10,500 psi? 11,000 psi? Where do you draw the line?

Yes, these guns were designed for those kind of pressures, now my shoulder not so much....

But I can't think of a reason to do so.

Waterfowl?

Yeah but..... "This in turn tends to eventually crack wood and begin to break little parts within the action and trigger group. So, it is never wise or safe – and nothing positive is ever accomplished – by firing modestly excessive pressure loads in any shotgun."(Tom Roster)

And we all know the Repro's reputation, even with perfect wrist grain, of stock wrists breaking for 'no particular reason'.
You'll probably be fine shooting 10,000 - 11,000 psi loads - nothing negative may ever happen.

Dean, would you please cite a documented example or two of that actually happening.

We can all go back to older posts on the forum by using by using the Search tab at the top.
Here's one by Harry Sanders from October 4th on the thread about Brian Dudley's stock work.

"I'll chime in too. As soon as I drop the first birds with it I'll show the Repro that broke at the wrist under only recoil while shooting clays that Brian has put right. I believe he has some photos and the work is stellar. I've just been waiting to get to my Grouse and woody woods to put it to use. He stocked it to my dims and I don't shoot clays but my attitude toward the gun and Luck? I shot 74 in 100 the first time and only time out this summer with the gun."

So let me provide a bit more context. I plan to load some waterfowl shells (2.75 inch) for use in a 12 gauge Parker Reproduction. Therefore, I am more concerned about clean kills of relatively large birds (mallards and Canada geese) and less concerned about my shoulder. I am also concerned about the shotgun--not so much the barrels as the stock (a nice thin straight grip). Looking for your thoughts on maximum pressure for a modern and effective waterfowl load with minimum risk to the wood.

Victor, you may be able to get some meaningful advice if you can show us pics of the gun, showing the species of wood, whether your gun is stocked in Juglans Hindsii or Juglans Regia and how the grain flows through the wrist area.
