I find another 11x59R cartridge that may be very much like the .445 Grasset Nitro

civilian SFM with a unknown non- magnetic jacketed bullet, same oal like 8x50R Lebel

a shorter brass bullet on a 11x59R with SFM civil headstamp

11x59R blackpowder lead bullet load, lead lost the paper patching in the storms of time

if you reduce rim thickness and diameter of the first round you have the thing. I measure a .439 bullet diameter on the case mouth what will help to reduce pressure in the .451-.454 gras brarrels.
