[Craig0ry]

Is there really any problems loading either for .45acp? I usually load .451 200gr CMJ but I have alot of .452 200gr lead swc, will their be any issues?

.452 Lead is fine.

.452 should be ok. it would be better if you slugged your barrel, you may be surprised at the diameter, it may not be exactly 45.
going .002 over is not a big problem just work it up and check your accuracy. you may or may not notice changes and accuracy my actually improve.

.452" is typical for lead .45 bullets. In general, it is a fairly standard practice to have lead bullets sized .001" over standard jacketed bullet diameter.
