.38 blanks. Grog sells reloading information on disc.Ended up orderliness some zinc pushers and ogives from kak industries to reload my own chalk rounds instead. Got 3 m212 reloadable aluminum cases from Pace defense to house the lift charge instead of the 38 blank plastic cases.
@baboon do you recall what lift charge you used for the chalk rounds or were you using the 38 blanks? I am thinking of using 4-5grains of bulleyes as a starting charge but doing a bit more research
