You were the one that said it is DR Specific and I was the one
who bought up Shotguns.

As to "Are Shotgun actions suitable for building DR's" ?
the answer is Yes they are.

Quite a few 577 Light Nitro / Nitro for Black Powder 577 3 2/4"
Double ifles have been built on Greener Shotgun Actions.

Marakai has one and he posted a link to his story about it the other day.

That gun which I sold him was built at the same time as
another one + a Cape Gun - 577 / 12 Gauge. There were
other DR's before this including 444 Marlin.

Ruger Red labels have been made in this country into
375 Fl Mag and 500 Nitro.

Re "I would be very interested to see a Lancaster wrist breaking back lock action, apparently they were easy
to open but a bastard to close, so struggled for popularity. Our unlamented snake oiled yobbo was clearly
unable to work a pitch with that one.

Sorry, Sold my Lancaster DR to a mate in the US and my Lancaster shotgun to a mate here.

As to "unable to work a pitch with that one"
If you are taking about "unable to work a pitch with Self Opener's"
What about all Purdey's and then the Holland Sidelock post approx 1922/23 when they
went from the AB Action to the Patented Self Opener ?

Finally, in regards to "apparently they were easy to open but a bastard to close"
do you really close your own gun. That's what loaders are for.
I strongly suggest you get yourself one, it makes shooting much more enjoyable.

I can recommend a few if you want but not sure which part of Oz you are from.
