that 311291 has been around what 100 years!
lots of 30/30s have short throats. Old trick from a old timer for getting your crimp in the crimp grove when your cartridge OAL is a touch to long for throat , cut your CASE length back a bit. Watch your powder charges as your reducing case capacity.
I have a nice mold I picked up from Ranch Dog its a 165 gn flat nose designed for the 30/30 it works well in every 30 cal platform I have ran it through, it will even cycle in the M1` garand.
NOE bought out Ranch Dog I believe
