I purchased a Lyman 12 ga mold from my lgs. I ordered it online from a used section of their site. I assumed that it is a sabot slug mold because I wasn't aware that Lyman had even made a foster slug mold. Then I started reading a bit here about the Lyman foster slug molds and how they are a problem because of their as cast diameter.
This mold I purchased didn't have any part numbers or specs listed but it was cheap enough to gamble with.
In the event that it is in fact a foster slug mold, what is the possibility of taking a Lee sizing die that I have no use for and reaming the hole out to the correct diameter to swage the foster slugs down to fit in a shot cup?
Have any of you attempted that?
Thanks
