44-90 Sharps Necked

My question is the bullet. I an having difficulty believing the bullet goes in this casing. I do believe the casing is UMC manufactured.
Opinions please?

Definitely a U.M.C. case and definitely not a U.M.C. bullet. Notice the absence of a case mouth crimp. Looks to me like someone’s homemade version of a Mead patent explosive bullet.

Thanks.
Basically my thoughts also.

The 44-90 necked as loaded by UMC didn’t have a case mouth crimp due to its use of a paper-patched bullet. In many cases PP bullets can be plucked out of the case as they are held only by a friction fit. Jack
