Headspace: more toward min or max??

Do you guys headspace more toward the min so shelf ammo or fresh brass is a tight fit, or toward max for extra powder room, etc?
 
Min to +.001" are my tolerances. The reality is it really doesn't matter. You'd be hard pressed to see the difference on the target.

Interesting. With most guys full length sizing, the min makes sense.

You adjust the die to fit the chamber. We're talking about the thickness of a piece of paper from min to almost the no go. The unfired brass is usually short by about .008" . Now if you use a piece of unfired brass as a gage you need to cut the neck and a small section going down the shoulder. The reason is the radius at the neck shoulder junction doesn't match the chamber. YMMV

Gotcha. Kind like how 280 ammo fits in a 280 ackley chamber but the headspace is .040” different :)
