Not familiar with Norm, if someone wants to PM a link that's fine. Not really aware of the pros/cons/process of cast.
This was the Hornady at 100 yds, with a 9mm casing for reference. Not bad, I'd say. This was the last splatter target with contrast that I had. I had to use paper with the triangular targets for the Prvi and it got ripped, it shot kind of to the right, unless it was me. If I recall, I've not had good success with IMR3031. Not sure if it's the projectile or the powder. I did have to contend with a guy who setup literally three feet from me with an AR with a big muzzle brake. It actually knocked my empty ammo boxes off of the table I was using, which was kind of annoying. Kept blowing my hair around. It might've affected my shooting.

Tumbling the brass now.
