What uses a .311 bullet? The 303 Enfield, the 7.7mm Japanese and the 7.65x53mm Argentine. All of these are military rifles. Which automatically makes it illegal in many countries, eg, France.
Even Woodleigh does not offer a solid in this caliber. A solid is meant for deep penetration on dangerous game. The .311 would not be legal throughout most of Africa today for dangerous game, simply because it does not develop enough energy.
Patterson shot lions with it, only because he had no other choice at the time. It is not the round I would want for such activity today.
If there was demand, then the bullet makers would produce it.
