I went thru some swagin' posts, the stuff on core moulds and cut off tools is apropos, but all I want is to make 45 grain round nose (or something near to it) boolits for a 22 Hornet. As much as casting is fun, production of 225415s is slow.
Knurl or cannelure for lubrication?
Round or RFN? Is there a profile that is difficult to machine for, and therefor undesireable?
Speed from 1,000 - 1,600 fps. Plain base is fine, the 22 Hornet has a neck long enough to seat the boolit so the base is not below the neck.
