what is your lightest load you ran on 300blk supers

Just looking to see what people started out loading with their 300 blk. I plan on using h110 and 147 grn mil surplus pills. I have seen some starting as low as 14 grn on the internet and others take it to well past max at 17.? grns so kinda skeptical since I have heard h110 does not like to be undercharged. But also has a tendency to pressure spike rather quickly....
If it helps I will be shooting out of a 16 inch barrel with carbine length gas system.

Not new to reloading but new to 300 so please elaborate on your findings please.

thanks

I haven't loaded anything under 180 gr. and those were super. I got some 230 gr experience.
