I read Sandy's question to ask who sets their fl size die to only resize enough to easily chamber/extract. I do, as it minimizes case stretch and makes the brass last way longer. Especially important with more expensive brass like 204 and Grendel brass. I strive for 3 or 4 thousandths shoulder set-back. For years I did the trial and error method by chambering a piece of brass, setting the die down more, chambering, etc until it just chambered and extracted easily. This whole process became way easier with the Hornady case gauge set. Empty pistol brass will work for this gauge also but the Hornady set is much nicer. This is for ammo used for normal hunting and target shooting/plinking.
Now if I was loading defensive or "shtf" ammo I'm in a different mode entirely. I would want it sized to minimum.
