Shadow,

It would also be an easy matter to run a 9x25 Dillon reamer into one of these 357 Sig barrels and have another 9x25. About 90% of the work would already be done.

Just a thought.

And if it gets close on the numbers, I'd also take another barrel for the 1006. I'd convert it to 9x25, since I've already got the reamer......
