AR Comp and SMK 120 - looking high and low for some data

[FLshooter]

I have a ridiculous amount of AR Comp. Over 14lbs. I wanted to try it for my 6.5 Grendel.I couldn’t find load data. So I went to space Coast bullets and I asked the owner. He told me with ELDM 123g bullets,I should start at 26.5g AR Comp.
I started at 26g AR Comp and worked it up to 27.5g. 27.3g is the sweet spot for my rifle.Did not try it yet with 120 g SMK bullets yet, Because I already have a load worked up w/H335 . But,if you work up from 26g w/120g SMK,you’ll be good.
