5.7x28

Correct me if I’m wrong on this, but I believe it’s a tricky round to reload. For one, there’s a coating on the factory brass that needs to remain, so some types of brass cleaning will strip that. Second, and this is just from reading some US forums, it doesn’t take much to create too much pressure or create unsafe rounds.

Take this as third hand info, but what I read led me to choose not to reload this round.
