That's immaterial, a sub 12 rifle must be sub 12 with any & every pellet so you test various pellets for muzzle energy in the same way that you test them for accuracy rather than just chuck anything down the barrel.

Those two should give higher readings & final energy should be set with whatever's highest which may not be your everyday pellet.
