[QUOTE="swampratt, post: 3600956, member: 15054"] I got a bunch of LC-05 .308 cases 500 of them to be exact. I prepped the things to the last degree and sorted by weight to the last 2 tenths of a grain and even sorted bullets by weight and sorted bullets by Ogive to base length. I did that because I had a very difficult time getting those LC cases to shoot a tight group. Did all that sorting help.....NO In fact the precision sorted rounds shot terrible. I was not annealing at that time and not neck turning either. I did sort after sizing though so all cases had same OD and ID in the neck area and if one seated the bullet easier it was culled. For an experiment during all this I took 3 cases that had the lowest weight the highest weight and a middle weight and loaded those also. Clover leaf group from those 3. Best group of the day. I even tried sorting by case volume..I used BL-C2 powder trickled through a funnel slowly into each case and card it off without bumping the case which will settle the powder a bit more. No positive results there either. I finally gave up on LC .308 cases. My Winchester cases shot way better. And I only sorted those by the way the inside of the bottom of the case looks and Neck ID and OD after sizing. If you look at the base of the Winchester case inside some have a raised ring like a nipple. Others are totally flat. The early ones all had the ring. I have a sneaking suspicion winchester farmed out case building and the cases became different. I do not mix those. [/QUOTE]
