Awright,
I am consolidating into new tooling since learning what the gunsmith had to say about my King Cobra. Most important number is .359, the chamber mouth diameter, according to his pin gauge. Since I only have RCBS factory-dimension carbide dies, I get hour-glass ammo, size-on-seating, leading and accelerated wear on cases. The LEE universal expander only puts a flare on the case mouths. They'll fit, feed, fire and function, but that's about it.
Lyman Cast Bullet Handbook describes slightly larger inside dimensions on a .38 Super sizing die. Has anyone tried that to size .38/357 for cast lead?
I recall that someone makes custom-diameter inside neck expander plugs, compatible with the Lee Universal neck expander dies. If so, who?
Any suggestions on expander diameter, to secure the bullet without size-on-seating?
Would the suggested bullet diameter be .359 or .360?
