Long-time caster and lurker, joining discussion for the first time with a mould question.
I have an Accurate one-cavity iron mould for a .30 cal rifle bullet with a long nose. Unfortunately, my instructions to the mould-maker were flawed, and the nose diameter is .010 undersize, so (obviously) the nose cannot ride the rifle lands. Aside from my hand drill and some valve grinding compound, is there a reasonably precise and inexpensive way of increasing the nose diameter of this mould?
