WildCattle,
Thanks for the input. Not sure about it being originally chambered in 35 Winchester as the rim on the 35 Win is bigger than that of the .350 G&H and the gun is set up with auto ejectors designed for a rimless cartridge rather than a rimmmed cartridge like the 35 Win or 9X57R. Also I believe the 9X57R has a .354 rather than .358 bore diameter. Again this is all speculation on my part. It is my understanding the rifle was built in the 1930's which would be the proper time frame for the .350 G&H.
Also, I am not sure what you mean by the proof marks posted on GB (IIRC), can you further explain. I purchased the gun from an individual so I am not sure we are talking the same gun.
Skeettx, Thanks for the links I have reviewed this I am still looking for some additional load information.
Again thank you folks for the input.
