I recently asked the same question about when is my brass buggered on another calibre as there was no apparent signs after 13 firings.
So I just figured as I use the same method for all my calibres, it's REM mag brass for you, it's the initial stretch iv heard of that ruins case life. Maybe I'm wrong but I have no other explanation when it's compared to my other calibres.
As I say, whatever your doing is working

My rifle may have a close spec chamber so the initial firing has minimal stretch? Ive only just FL sized this brass today and only because I could, no because I needed to. Would have been good to check with comparator before I bumped it to see. I will have original dimension in my reloading book I guess. Ive never had may troubles with the Blasers as far as fiddling with dies etc to get things to work.
