Nobody has any scientific data on how long it takes to "wear out" a resizing die using brass, so it is impossible to yardstick if reloading steel cases accelerates wear. My personal anecdotal evidence says it doesn't, but I'm also using 35-year-old dies that have all ready seen lord knows how many thousands of rounds resized through them before, and I am NOT running a side-by-side, round-for-round control set of dies to compare wear rates. Until someone actually does this, anyone claiming such is just guessing.
I have also had good luck reloading steel .223 and .45 ACP. As was posted, sometimes the cases last through many loadings, and sometimes not. Never have I had any problems with reloading steel (or shooting reloaded steel) that I have not also had with like brass.
At my range the cases are free and plentiful (while brass is not -- there are virtually no brass pick-ups available at my range).
I tumble in stainless media, and that removes the coating (either the polymer/paint or lacquer). I dry with compressed air, and after resizing I don't re-tumble (leaving just a hint of the sizing lube to protect against oxidation/corrosion.
There are many many things in life that are possible to do. That doesn't make then the thing to do however.
I know you have tried this before, and I know you share this very same words in every thread which discusses reloading steel.
Never have you presented any evidence for feeling this way. What is it that you saw which leads you to this conclusion?
Until I see some evidence that there is some negative effect, negative impact, to reloading steel cases, then I'll continue to do it as my personal experiences and observations reloading steel have been very positive (and quite frankly I have yet to see a single negative).
I am always, however, open to new evidence and open to re-evaluating my opinion upon evaluation of that evidence.
