[QUOTE="Lenny Foffa, post: 2270612, member: 100742"] YES!!! Always!!! For Hunting loads I try to keep with in 1/2 Grain . Example .270 Win, in Light Win Cases. 185.0 to 185.5 ; Next batch 185.6to to 185.9 . After buying several bags over several years you will end up with several Blue Plastic Boxes of Fired Brass . 25 to 30 rounds in each box, labeled 270 Win Case weights . 185.0 to 185.5 , another 185.6 to 185.9. Another box 186.0 to 186.5 and on and on. I weigh my new brass AFTER I have checked over all length of the each case ; Trim If Necessary ; De Burred and Chamfered the necks, De Burr the INSIDE of the flash hole, and cleaned the Inside of the necks. Then weigh each of them, and put them in the correct box with their brothers. My personal thinking is simply this.
