Kind of new to the reloading game (about a year and a half). It suddenly occurred to me that I may be wasting some of my time. Is it necessary to size and trim new brass?
I just completed a major project, loading 1000 rounds of .45 ACP, and I resized each of the brand new Starline cases.
It ensures proper chambering, consistent neck tension, and reliable extraction and ejection.
I can say there was resistance with each case as I sized it, a telltale sign that they needed it.
For clarification with the other fellow who mentioned only needing to full length resize, what he said about only needing to resize for the first firing and not thereafter applies strictly to brass used in bolt action or strong single shot rifles that have the rigidity to only require the case neck resized for several firings after the initial one.
Always full length resize for all handguns and all lever action, pump action, and semiauto rifles.
To have consistent neck tension or not...that is the question?
I don't for pistol ammo.

You don't...but you do, sorta. When you bell the case mouth, that trues up the mouth and neck of the case. So, you may not resize the base/head, but during a normal reloading process for pistol ammo, you do address any concentricity issues.
Well, if the Lady isn't complaining, then yes... it DOES!Thanks ModernGunner, but my wife hasn't complained lately so I don't think that answers my question.
