Not that it's all that compareable but I use 4831sc exclusively in my .338 win mag with CCI mag rifle primers and the 250gr (heavy for caliber) bullets of various manufacturers. my accuracy is always a cloverleaf pattern with the holes touching each other and it has been chronographed by my very best friend to a variance of 20fps velocity in all temperatures from 10F to 90F, even with different brass, lots of powder, and bullet manufacturers. For these reasons, it is my go to powder for heavy bullet loads as it has also shown the same performance in 30-06, 264 Win Mag., 308 Win.
