Overbore has become a term which gets tossed around but has very little to do with reality these days with our modern powder formulas.
It's a term out of history.
In that same vein so is the concept of a barrel burner. Modern, cooler burning powders with new additives and coatings means that throats erode much less rapidly than before.
WOW !!!!!!!! you live in an internet dream world based in fantasy not reality
