OK, taking a stab a this,
Do you have 450 3 1/4 inch Nitro Express Dies or do you have
450 3 1/4 BPE dies?
I know dumb question but had to ask
The NE case is slightly bigger than the BPE case and that could be the concern.

Mike

p.s. And I did not see the BPE die set as a choice on the Hornady webpage.
