I've been shooting soft .358 bullets out of this particular gun(SW 14-3) for a long while without ever checking dimensions.Accuracy fine but occasionally I'll get a bit of lead in front of the forcing cone.Forcing cone appears nicely tapered
I can't complain about the accuracy as stated , but do you think it would be any benefit to opening the throats up?
My Blackhawk was .448-.449 throats and I opened those to about .453 and it was night and day Accuracy improvement.
