I do need to verify that the seating die is out of contact with the case. Again that is why I and looking a length. Too long of a case could be hitting the seating die and starting to crimp before I get to the Factory Crimp Die. It seems the issue is either the Flat based bullet or my size die is not pushing the shoulder back?
I size on a Lee turret press then trim de-bur and clean. Now I have good clean brass to run through the press. If the shoulder is not set back correctly the trimmer I use refences the case neck length off of the shoulder and that could be the issue.
I don't THINK the crimp die is the problem as I have loaded ~10,000 rounds without touching any die adjustments?
SO I need to gage everything out of the size die and then again after trimming to isolate the issue to flat based bullets if all dimensions are good?

Any and all comments welcome and appreciated. After all the hours in just processing the brass I hate to trash 100 rounds!

I will look into that too.

Bullet seating die is screwed in too far. Basically crimping the bullet while seating causing the shoulder to bulge like that. Trust me and donít ask how I know.

Thats what happened to me on 8mm mauser once.
Shoulder was fine until I seated the bullet. I was not using a die that locks the nut down and it moved on me when I was screwing it in.
The lee dies come with a nut that can move on me. all my seating dies, rifle full case , and FCD all have a locking nut on them so they don't move anymore.

Yup, Unscrew the die out 1 turn. That will give you lee way on cases that may be a little too long.

Thanks again, I'll see if I have any more room to back it out and still get the OAL I am after.

Just happened to me when moving my seat/crimp die from my AP to my single stage. I didnít adjust the seat when going to the single stage and crushed the tops
Of the case. Figured it out when I put it in a gauge.

I sized a WHOLE BUNCH of cases and trimmed them. My trimmer (Worlds Finest Trimmer) was either packed full of Brass or out of adjustment?

Cases were sticking out of the case gauge, over max. Cleaned and reset to 1.75 minus a little bit. I will try again with cases that are to dimension.

(It is a little case with a bearing and an End Mill.)

I have been using a Lyman trimmer for maybe 45 years or so(last 15 years with a drill instead of crank). If you mount it in a comfortable position, it can be very fast and, once set, it doesn't change.

I use the WFTs on a drill press at a higher speed(than a hand drill). They tend to throw the shavings out the side ports better. I still check/reset them before running a bunch of brass through them.
