Lee 454-252 SWC

[Guesser]

I purchased a NIB Lee 454-252 SWC DC mold. Never used, complete with little pocket size Lee product catalog. Looking at the current product listing on site I see that Lee has changed the mold description to 452-252 SWC.
Has anyone here used both? Are the old ones accurate to 454?
The current product # is 90356, this old product doesn't have the 5 digit # on the box.
Any comments greatly appreciated.

Have an old one. Use it a lot in 45 Colt. Size it .452 and don't have any on hand unsized. Will cast probably this weekend and I'll check size.
