[QUOTE="Opa-lopa, post: 2441892, member: 108809"] Meaningless. There’s a 5% MINIMUM variable engraving pressure shot-to-shot that causes about a 10 FPS swing in muzzle velocity for the same charge weight. The ONLY way to find out what a given charge weight does is to fire a larger sample. A single shot at one charge weight gives you a muzzle velocity that could easily be higher or lower by a significant amount. In a single shot “ladder”, you’d be far better off looking at all the velocity data and drawing a line (least squares fit) thru it. Power weight is energy, how could you possibly put more in & not get more MV out in the long term? [/QUOTE]
