Has anyone tracked lot to lot variation in powders to see what an expected extreme spread in MV might be? I am new to reloading and was fortunate to start with about 10lbs of the same lot of H4350. I just started a new lot today and noticed my MV with the exact same load went down by about 37fps.
The only thing I can think of is that the humidity of the old lot has stabilized around 30% and this new lot is still more moist (have not had the opportunity to measure it) which would make it heavier and thus less actual powder by volume in my case.
If anyone has any ideas or facts about this I am all ears.
Thank you
