T. Hall, moulder of young minds! (look that up in the dictionary).
The current issue of Rifle Magazine has an interesting article titled THE CRUCIBLE about J Rigby's attempts to barrel the first .450 Nitro Express. They "wasted" (Rigby's term for failing proof) four sets of barrels before they got it right.
Not as technical as you need but an inspiring read nonetheless. It's available for download here, the entire article starts on the 15th page of the .pdf.
