Requesting load data for 223 Rem with 62gr FMJ and IMR 4166

[tailbon3]

The title sums it up. I have a bunch of 62 grain FMJ boat tail 223 bullets. They are in a bag from Cabelas with the TopBrass brand. They do attract a magnet and aren't hollow points. I imagine they are military pull downs or over-runs. Does someone know start/max load for that combo? I was thinking of starting with the Hodgdon's manual's load for 63 grain Sierra SP. That starts at 21.7 grains.
Thanks in Advance,
tb

Start and max will depend on the powder you have chosen…whether it is ball or extruded will usually help you decide the proper primer to use. I'm thinking that the Sierra sp will also have a different ogive
