Thank you all, I will first look into Magnum primers and move on from there.

Hello, I am new to this site and a novice when it comes to reloading. Since powder is difficult to obtain I found a supplier with TCM powder and purchased it. I found no data on reloading for 10mm and wonder if anyone would have any information or did I make a mistake on buying the powder? I have 180 and 200 grn projectiles.
Thank you for looking at this thread.
