Superperformance is quite a bit faster than h4831 is. And the data isn't even close to similar. And there is almost nothing they cross reference to each other.
H4831 is a slower powder made for heavy for caliber projectiles.
Superperfotmance is quite a bit faster and made to push light to medium weight projectiles. Superperformance doesn't have a whole lot of uses,as in not very versatile,like h414 or varget it,however the loads it is good for tend to show a velocity increase over most everything else listed for the bullet weights it's suitable for.
