HI Jore, I think I have a packet or two from when I had a .375x2.5. and I have a dealer contact who definately has some, he also has significant numbers of other Woodleigh calibres in his store.
The bad news is that we are in Australia. The possible good news is that he is experienced in shipping rifles and shotguns to USA , in fact he has just sent of a large ci=consignment. I will ask him if he has the horrid process again. I will ask him today and get back to you.
One of the double rifles shipped was a beautiful H&H percussion double with damascus barrels and all the accessories. It may show up in a Rock Island Ausvction soon. cheers hendo
