Hodgdon only likes to publish Superformance data, when the powder manages to exceed all other competitors' velocities with the same bullet.

Since Hodgdon doesn't provide the "most accurate load" notes, like most other data sources, there's no way of telling if that extra velocity is actually conducive to good accuracy (in their test platform).

Considering my own experience with .243 Win, and 4831-class powders.... I'd say you're seeing an unpredictable, incomplete burn, and wasting the powder. Step your burn rate up to something between say, H380 and IMR/H 3031, at a minimum. The 65 gr V-Max is way too light for a 4831-class powder.

I know that doesn't directly address accuracy, but you're better off with a powder that is more appropriate for the load. After you get a few rounds down range, the barrel should 'calm down' and "settle in". Only then, will you be able to see the rifle's true accuracy potential.
