Greetings Padox,
AR2213 is a little faster than AR2213SC/ H4831SC and a little slower than IMR4831. It was manufactured from about 1986 and discontinued about 2000 but the last powder was likely made earlier than that. You will likely struggle to find much data for it and none of it will be recent. There was some data in the ADI November 2000 Handloaders Guide including some that is extra hot to dangerous. Lawn fertilizer perhaps?
Regards Grandpamac.
