I measured the end of the chambers on my GP-100 and noticed that the diameters were about .355". I couldn't make a 9mm plated bullet go through the chamber without stopping. I load .358" lead bullets and .357" plateds.
Would this chamber size affect performance or accuracy? It seems that the bullets would be swaged to a diameter smaller than the barrel before they reach the forcing cone. However, there are no signs of wear or roughness at the front of the chambers and no lead or powder accumulates there.
Is this normal? If not, what are the usual chamber diameters for a 38/357?
Thanks for the advice.
