I just found a copy of my post from May 2019, on gold dots and Pro hinters, with CFE.
This was of course for my rifle, YMMV so beware. a 20" Howa HB bolt-action, not an AR.

First results with 120's (pro hunter and gold dot) and CFE
I took some CFE223 powder and worked up 2 ladders, for the 120 pro hunter and the 120 gold dot.
I used a range of 30.8-31.0, 31.2, 31.4 for both bullets, using Hornday 1x brass and cci450's.
This is all for my howa 20" HB, and I had tested OAL's for both bullets, the pro hunters look to go 2.240, the Gold dots 2.340.
The pro hunters I seated at 2.215" and gold dots 2.240 (I had used this before with a few GD's I shot).
Each powder charge was for 3 rounds, mostly to see where I was regarding MV's out of this barrel.
I didn't see much in way of data compilations on the forum for either (my search-fu I guess may be lazy! lol!).
120 Pro Hunter
30.8: Avg 2510, sd 11.
31.0: Avg 2518, sd 10
31.2: Avg 2537, sd 7
31.4: Avg 2540, sd 13
120 Gold Dot:
30.8: 2477, sd 15
31.0: 2465, sd 30 (this one had a 2430 - really low for some reason)
31.2: 2497, sd 18
31.4: 2522, sd 14
No conclusions this early on, everything shot well. Groups were generally ~1.0-1.25 with a couple of stonehenges, but not my primary focus for this setup.
I'll probably do some more with the pro hunters at 31.2.
Also, the pro hunters had maybe a bit harder bolt lift at the 31.4 but no flattened primers.
