Just re-read vol. 1. Did you ever go back and re-do the Mexican Match ammo? It was obvious that 24.0 grains and the Ultimack did not mix well, but what about 24.5 grains? Or 25.0? If the U rail makes the barrel stiffer, then if you find an accuracy node it should be somewhat accurate. As always, the keyword is ‘if’.
