If you like to seat and crimp in two steps these spacers I made work great, install the spacer, seat the bullet, remove spacer and crimp

Sport45, I knew I was wasting my time explaining the use of shims when I failed to convince anyone the die had to be indexed (.000-zeroed) first, I gave up when the concept if raising and or lowering the die was solely dependent on where the shim was placed. Again, RCBS sold 38 Special dies, then they sold 357 Magnum dies, after that they sold the same set of dies with a spacer that worked if the rleoader added the shim between the press and locking ring, that worked if they did not adjust the die every time they used it, like me, I do not secure the lock ring to the die, I secure the die to the press with the lock ring.
Dillon started the seat on one and crimp on the other, there is a conflict when crimping while the seating, the bullet is moving down while the bullet is closing in around the bullet, in the perfect world of ‘all cases being the same length’ that works, maybe. I am not a fan of removing the die to add a shim, and I am not an easy sale.
I have a Dillon 550B, I seat and crimp with one die, I use a powder lock out die, I could seat then crimp on a single stage press, but that is not Walkalong said he does, I did say I have a 45 ACP that likes new, store bought, factory ammo or ammo I load and crimp with a full length sizer die, not all of the case just enough of the case to improve the appearance, to improve the appearance I remove the bulge, the bulge that makes the case look like it swallowed the bullet.
seating, crimping and adding shims, taking shims out and then there is the ‘where to place the shims’, requires keeping up with more than one thought at a time, Sprots45, you are correct, the crimp is adjusted first then the seater stem/plug is adjusted, not the other way around.
