I use a Grendel shell plate and pins with both formed Grendel brass and factory ARC brass. The pins do seem to be a little too small when seating. I just attributed that to potential tolerance stacking with my setup. I use a Whidden free float toolhead and a micrometer seater. Occasionally I have to 'tip' a case with my finger to line it up with the seater. Every once in a while my mandrel requires the same.
