[QUOTE="Kansaswoodguy, post: 1332410, member: 83267"] Also you said you use a powder throw I do also that is not the issue consistently using one can be however. I load the throw with powder and throw 8 or so charges into a cup dump it back into the hopper and then load all 50 or 100 cases never bumping the table I don't even keep the cases on the same table as the powder throw. I want the same density of powder in every case. I firmly believe the 1 part lanolin to 10 parts 99% isopropyl alcohol spray lube making sure to get inside the necks helps lower SD I also polish my expanders with at least 500 grit. I use walnut tumbler and have heard of guys having issues getting low SD with stainless or sonic cleaning. Are you trimming your cases? [/QUOTE]
