Hypothetically speaking, if one to build a new rifle in 9x57 could you do so by using a .358 barrel instead of the original .356?
Would you be able to use 9x57 dies or would custom ones be required.
Lastly is there much benefit over the 8x57?

Anyone have some real 9x57 velocities as most books make it sound like a weak version of a .358W, but in my mind it should be a little better?
