Shiloh 40-50 SBN Problem

I finally got around to trimming (1.690" OAL) and forming brass using C4HD sharps-shiloh FL set. They are 0.050" short of going all the way in. I dykem'd a case a tapped it in and it shows it is stopping on the shoulder. Anyone else have this issue. I will probably have to talk to Shiloh and C4HD.

After checking my PTG reamer and other measurements it appears that the FL die is cut about 0.050" to deep. I will have to put it to C4HD.
Thank you,
Charles

I had the same problem when I had mine. Same dies but a reground reamer from a 45-70. Wound up putting them in my lathe and taking a little off the dia. Fire formed and they were fine after that.

As predicted from a prominent supplier I am getting nowhere with C4HD. I will write up the entire process once I calm down.

Bohemianway,
      You can correct your full length sizing die by removing 50 to 100 thousands off the bottom of the die, thus setting back the neck on your brass.  Keeping the removal 100% square would be nice but not necessary as the press would keep the die square to the brass.
     I have made similar adjustments to 303 brit die and 40-82 silhouette.
