Hi folks. It has been quite a while since I have posted. I am basically a shotshell and associated loading equip. collector. However, we all know the auction box lot deals can contain anything. Because of that I have accumulated a number of rifle and handgun cartridges I know little or nothing about. The following cartridges were included in a lot I bought last week and would appreciate any info you can provide.
HS: 12 o’clock, 1776. Center, oval with U impressed over left side and S impressed over right side. 6 o’clock, 1876. Copper, inside primed case. Case lth - 1.59, lip - .49 (best guess, no longer round), base - .52, rim - .60.
I believe a 56-50 Spencer but has no HS or C.D.Leet crimps and no case crimps. Case base measures .56.
HS: REM-UMC 6 m/m U.S.N. RNL tipped I guess steel bullet.
