[QUOTE="nkyshooter, post: 2104307, member: 83787"] +1 on some "lubrication" on the inside of the necks for brand new brass especially ... Once they are fired, if you don't sonic clean, you will have some carbon inside the neck that should keep the expander from scoring the brass - but - as many have said, lube is a good idea ... some would say "required". FYI - if you use a Lee collet neck sizing only die you do not need to lube the inside of the necks ... My accuracy process for all my rifle cartridges for which I have these dies is as follows: [LIST=1] [*][B][U]If [/U][/B]FL is needed, I use a body die (or a bushing die with bushing & stem left out) to bump shoulders/walls and leave neck alone (req's lube) [*]Neck size with Lee Collet (no lube needed) [*]Check for and trim/chamber/debur as needed [*]Prime [*]Charge [*]Seat with a sleeve based seater die of choice ... (forster, redding, Lee, hornady, etc) ... or a Wilson straight line if you are trying to shrink groups to BR Competition size [/LIST] One final thought as you mentioned you are using the custom comp dies ... bushing based right? ... maybe double check the bushing to see if it is too small in diameter ... if this is NOT a bushing die, you could try removing the stem, size and then measure internal and external dimensions of the neck to see if the die is "too tight" at the neck resulting in more expansion required than should be necessary on the down stroke over the expander. EDIT: good call from [USER=105102]@Ckgworks[/USER] - he was putting that in as I was typing :) [/QUOTE]
