Well, it was not obvious to me but I finally figured it out. Most ML in .50 are actually .500" groove diameter.
"It should be obvious that the DOC-designed .451 bore is merely a modern .458 barrel with 1-20 twist and .035″ grooves. Likewise the White .410, which is a modern .416 barrel with 1-16 twist and .035 grooves. The .504 is a modern .512 barrel with 1-24 twist and .004 grooves."
The .504" is the most narrow dimension, the largest "pin" gauge that would fit in his .512" bore. They use soft bullets that upset to fill the bore or sabots. His initial notes speak of his fascination with the Whitworth system. I can see now.

So this is why they take "special" bullets.
