Have a small shop project, easy pretty straight forward. A 310 tong tool sizer die that came to me missing the push through rod so it needs replaced.
On one hand I'm thinking a mild steel would be ok however I feel it would not take wear very well.....on the other hand something like 0-1 would be too hard (harder than the die and the base wear plate and cause premature wear on those parts....
A friend said 0-1 should work very well esp if I don't heat treat it (was not planning on it) but I'm not convinced.
The die is a .358 die and though I'm not 100% sure of the length the rod needs to be I'm assuming its about the same as the .308 sizer die I have as well, just a different diameter.
