That 0.003" isn't going to cause you any problems, even with jacketed bullets. Furthermore, you can swage jacketed bullets in a sizing die. I regularly do it with Lee sizers, swaging .338" jacketed bullets to .332" for a .330 groove diameter. The rifle has a pressure sensor installed, and using the same charge used for .330" bullets, the .332" bullets raise the chamber pressure an average of about 150 PSI. If you doubt the issue regarding the 0.003", read Ackley.
