Quite a few Single shot 12 bore rifles were built over here
on the Greener GP Action. They turned out very well.
The other I think is the Ruger No 1 or 3 actions
but can't clearly remember.

I gather the Greener GP Action are strong actons
and easily take a 12 Bore barrel.

I am not a gunsmith and not into BP Bore Guns but
I liked them and they are very accurate.

Though I would hate to regulate one to the sights !!!
