Re: Which cartridge to use in a shotgun conversion

This is one of the things on my bucket list since I was young. Other things include gutting and rebuilding a house, restoring a car and building the engine. I have a group of friends who are smiths and hobbyists. I started out building muzzle loaders, then cartridge rifles, now I think it may be time. I may never fire it but I will not take bets on it. The shotgun is a 1924 Belgian based on its proofs there is a lion over a large PN which is black powder proof I am not sure on Nitro since the proof chart is a bit ambiguous. There is also a large oval with a crown over it and E LG * German BP proof, and a French looking EL which is the provisional proof 1924 on.
I have plenty of 50-70 this would make a light recoiling rifle with low rear thrust. It may take aq while but I hope I have time.
The old Accurate Arms (red) loading manual has data for .50/70 with smokeless powders. I recall they used AA2015?, seems to me and got REALLY impressive velocities at quite low pressure.
I don't have that manual. My now gone buddy did & I never wrote it down.
