Not probable maybe, but still possible.

So the mid ranges for the two bullets you are comparing here are 6.4 for the FMJ and 5.8 for the lead. If it were me I'd start with the 5.8. But that's just me and my approach. Others may have different recommendations.
I had made up 5 rounds each at 5.4, 5.6, and 5.8. Sounds like I need to do 6.0, 6.2, and 6.4. Will need to see what I should do with the 5.4 loads.
