if you are more interrested in this load pls have a look here
i got a reply from w44wcf at Cascity :
My apologies for not going into a bit more detail about the load that UMC made.

I had casually mentioned that UMC would have used a wad..... based on my making and shooting some of these cartridges the wad thickness would likely have been at least 3/16" (5mm) thick. They likely would have compressed the powder charge a bit first or compressed it with the wad in place. Hard to say.
Anyway, as I mentioned, I used PSB (Poly Shot Buffer) to fill the space between the powder and the bullet since I do not have wads of the proper thickness. Cream of Wheat or Corn Meal would likely work as well.
I found that historic loading when assembled as above, would produce groups at 100 yards in the 2-3" range from the bench.
He post a lot of very good info
