Kinda new to have any published data available. I have only read about the new round about a month ago and doubt it there is any data and reloading tools available this soon. I saw some speculation (forum guessing) the cartridge compares to the 30 Carbine. As for canister powders, there are "suitable" powders available for all typical/popular calibers, new and old, produced in the last 120 years, just finding a specific powder available now is a problem...
