24 inches is the gold standard for a reason. It gives you near-optimal velocity for the cartridge's design. You'll be within 50-75 fps of what a 26" tube gives you, but in a significantly handier, stiffer, and lighter package. It's the perfect blend for a do-everything precision rifle, manageable for hunting or positional shooting, but still letting the cartridge sing on a PRS stage or at the 1,000+ yard line.
