For our club's many re-enactments we load 2 calibers of
BLANKS: 44 Russian & 38 Special.
The Ruskie
BLANKS will work in .45 LC, .44-40, .44 Special/Mag and of course .44 Russian.
We have had no problem with brass expansion. Of course these are
BLANKS: Enlarged primer holes, real black powder, thin cardboard (paper)wad. Very little pressure, very little expansion.
Can't promise about the rims/extractors ......
Hope this helps.

(Emphasis on
BLANKS added for the benefit of the addle-brained who might make the dangerous mistake of thinking this would be safe a substitute when using
live ammo.)
