The cylinder throats are .429", not the chambers, correct?

There is absolutely no harm in using a cast bullet that is slightly larger than the cylinder throats. In fact I size my cast bullets .360", .432" and .454" respectively for my .38/.357's, .44 Specials and 45 Colts. The ONLY change I saw by increasing bullet diameter was a reduction in leading ahead of the forcing cone.
