Standard diameter for jacketed .45 bullets is .451; lead, .452. I'm not a fan of XTPs (load lead primarily) and don't know why they would be .452 dia.

The larger diameter is likely to raise pressures. If I were to load them, I'd follow standard reloading practices and start with the minimun recommended powder load for that weight in a jacketed bullet.
 
I agree with above advice. Save the .452 for a 45 LC or 454 revolver. You could develop issues including high pressure and chambering problems.
 
I never had a problem with anything .452" in any of my .45 ACP Model 625s or Glock 21s. In fact, I have a .45 Super equivalent load for my 625s that uses the 250 gr. XTP at over 900 FPS. It's extremely accurate and I've never had any indications of high pressures.

Call Hornady, they are really nice and you will get a kick out of their answering message.

Lead bullets are 452, plated bullets are 452

But my JHP, Gold Dots, XTP's and Golden Sabers are 451.

So good question call the folks who make them.:)
 
Drop them through the throats of your revolver! If they are not too awful tight( as in they wont pass) load them and shoot them.
 
I had a bunch of 452" XTP's that I got as bulelts for a M/L and they included sabots. I loaded them with bullseye and shot them through a Sig P220 with no problems. Seems that all hornady jacketed 45's run 452".
