Here are some pictures of my new acquisition. It came with the bayonet, the original rimfire breech block, a fitted center fire breech block, original follower. Brass follower for centerfire cartridges, and Stabler cutoff.
Unfortunately the forearm wood has been replaced with what appears to be a 3 band stock from an Armi-Sport 56-50 replica. Who ever did the replacement did an excellent job as the stock is well fitted to the barrel and receiver.
I have the original bands and am in hopes of finding an original 68 or 70 trapdoor stock that I can modify to fit this rifle.
Did a chamber cast and it is chambered in 50-45-400 aka 50 Cadet. I started a bullet sized to .511 into the barrel from the breech end and it engaged the rifling nicely.
Barrel is pitted but not real dark. The 3 groove rifling appears to be good.\
I cut down 50-90 Sharps brass to 1.3" and it chambers easily. I have 50-70 government brass on backorder from Starline.
I am using a modified Accurate 51-330S bullet. I had the crimp groove eliminated and increased the width of the lube groove 0.050" and the depth increased 0.050" to carry more lube.
Made 4 dummy cartridges 1.680" long and they cycle really well.
Special thanks to NDNCHF for all the posts he made concerning his 56-50 Springfield Conversion. I would have never gotten this far without his work.
