H322 was a dominant powder in the .222 Rem back in the day. Now I use it in the .45-70 and similar. It falls between 4198 and 3031 on most burn charts.
H322 is a favorite of mine when paired with a Beartooth Bullets PileDriver jr. in my Guide gun.
I use it with 55 FMJs in a 5.56 rifle, I have a metric schidt-ton of it.
