The problem a gun company has with fast twist barrels is that only 5% of the muzzle loading population (like the guys here) have an understanding of how to make them shoot well. The average Joe is going to buy pre-packaged sets of bullets & sabots or Powerbelts and stick 150 grains of powder down their bore. When they get poor results they will be saying to everyone they know "that company's guns don't shoot well".
