My RCBS carbide 357 dies are deep enough that I can load 38, 357 mag, and 357 max with them, I'd ass/u/me that they would build their 45 dies the same way. Be careful though, if your sizing die isn't deep enough you'll have trouble putting the rounds back in the cylinder.
I'd run one case through the size/decap die and get the mics out. You'll have your answer.
