I am interested in purchasing a 155gr to 160gr, 0.359 diameter NLG RF mould with a meplat in the 0.250 area for use in 357mag revolver and break actions. I have seen other weights with this kind of design, but none quite what I am after.
I am comfortable with CAD software so producing a drawing is not a problem, but I am pretty sure there are factors governing the ideal shape of a boolit nose that I am not aware of. Are there any general principles which I should keep in mind when considering how to shape things?
Alternatively, I am totally willing to just buy an existing design if one is out there...
