I have often seen the term "burned" when describing how the early single HT receivers got in to the problem condition.

Question..
What exactly is 'burned steel' as it related to HT/case hardening & the steel used in the '03?


If a piece is case hardened, however deeply,,and you don't want it case hardened anymore,,you anneal it.

Why couldn't the '03 be annealed and rehardened.
Wasn't it just being casehardened?.. or am I wrong right there..

What was the 'burned steel' thing that allowed the action the be case hardened in the first place (too deeply perhaps), but did something to the metal that wouldn't then (or now) allow annealing and re-case hardening.

Didn't the same guys ever 'burn' a Krag.


Confused,,but still shooting my Sedgley Sporter..
