Dan I'd look at your primer punch stem.
one other way around the neck 'donut' is to put it at the front instead of the rear.
I have no M-type dies so control neck tension through ball diameter.
this gives me what I want with a jacketed bullet, but not quite what I need with cast.
so what I do is use a larger ball to bump my case mouth against the little taper at the front.
an 8mm is perfect for the 30 cals. [7 for the 25, 243 for the 223, 30 for the 7mm]
I bump the case mouth and chamber the case and keep on going until I feel it scraping it's way to the end of the chamber.
then I back my seat die waay out and run the seater stem down lower.
the case mouth just enters the neck portion of the die and the boolit is pressed into place in multiple steps at each step I spin the case so it generally takes me 3-4 steps to seat a bullet.
[I have noticed this reduces run out]
I have also been known to use a different caliber die to seat boolits, I.E. 8mm lebel for 8 mauser, 45 colt for 44-40.
