Re: Bumping Shoulders Issue
FL dies are capable of being adjusted all the way down to the shell holder to resize the whole case (FL) or adjusted upwards to only bump the shoulder or upwards farther to only resize the neck.
The case that you use should have been fired in your rifle. Before you start this process put it in your rifle and close the bolt (I'm assuming this is a bolt action rifle). When you start pushing the bolt down you should feel some/slight resistance to closing
To better see my progress when I'm neck resizing or bumping the shoulder, I first lube the case inside and out. Taking care not to get too much lube on the shoulder, thus preventing ripples in the shoulders. Then I use a bic lighter to smut up the case from the top of the case down to the bottom of the shoulder/body junction.
You may be able to turn that lock nut over on the die so the rubber o-ring is facing up and outta the picture for the time being.
I then get the die started in the press and repeatedly run the case up in the die until I start seeing the smut starting to get rubbed off by the die. The case becomes shiney whenever it touches the internal parts of the die. I keep screwing the die down until I get the neck resized and the shoulder bumped back. You'll know when the shoulder gets bumped because not only will the smut be smeared or rubbed off in spots but it will also chamber in your rifle much easier than it did originally.
Note: once I get the neck resized and I'm trying to bump the shoulder also, I start checking the case in my rifle's chamber more often. If I have to re-smut the case again I will. Hope this helps. JohnnyK.
