Re: Virgin brass vs. fire formed
Accuracy wise, I have never really been able to tell any difference. I prep V brass just as I would fired brass but note it in my journal that it's V brass.
When I first started reloading 25 years ago, I read that accuracy wasn't as good with V brass as it would be with subsequent firings. I got in the habit of denoting V brass in my journal but never the firings afterwards with the same brass (i.e., 1st,2nd,3rd,etc.). Don't know why, guess it was my "mulligan" in case the groups were crappy. I hate those kind cause in the back of my mind I know I should try them over with fire-formed brass, just to see! OCD?
I have had some mighty fine groups using V brass in every caliber I have reloaded for. Some have been repeatable, some haven't. In my mind it holds about as much water as the full length vs. neck sizing theory! Who really knows? Just load, shoot and reload some more to get your "group therapy". lol. JohnnyK.
