That's FMC, not FMJ.
Not sure what they mean my FMC, but they draw a distinction themselves since they use it differently than the FMJ loading.
Also, if you look at the 230gr JHP loading at Allliant's website, it goes up to 6.4gr unique.
Lee labels that load as 230gr FMJ. Unique labels it as 230gr FMC.
There's one discrepancy. I'll find more for you later on.
