Tangolima: "Or just cull the short ones."
I can agree with that recommendation for those cases that are shorter than 0.670", which is the minimum size that extends to the maximum of 0.680". But I have found cases that are under 0.670 after firing that upon resizing still fall in the lower area of the .670-.680 range. The 50th Edition of Lyman manual tested .380 loads with cases that measured 0.677." I guess one can trim every longer case to the mid-point of 0.675" but I'd lose a lot of brass that falls below that measurement that is not likely to grow to it after firing and resizing.
