[QUOTE="boomtube, post: 372448, member: 9215"] "Any ideas what I did wrong? " Yeah. It's highly likely you are changing your die by massive amounts as you do "little steps." The full range of headspace tolerance of most bottle neck cartridges is about 7 thou. A 1/8th turn of a die is very close to 9 thou, being about 28% more than the total allowed range of headspace tolerance. Even half that. 1/16 turn, changes the shoulder almost 4.5 thou. If you want to see adjustments in the 1-2 thou range you gonna have to make 1/64th turns, which gvies a bit more than 1 thou sholder change. All that means you gonna have to learn what "small die changes" really amounts to. And, you likely gonna have to learn a different lever cadence than you normally use if you want any kind of consistancy at all. Push the lever fully down and HOLD it down for a full second, maybe two. And lube each case as nearly identical as you can too. Both things really do make a difference. [/QUOTE]
