Thanks, Paul. I recently purchased a Lee Load-Master 10mm Auto Progressive Press, may be looking for some expert advice on reloading some Nosler 10mm .400 180gr JHP with IMR HI-SKOR 800X Pistol Powder. I am still in the process of getting everthing set up. I have a friend that has alot of experience reloading rifle ammo but not pistol ammo.
