I believe what you have to do is find the right combination for that barrel. Sometimes it takes a lot of time, patience and resources to find what it likes.
I just finished burning thru over a 120 Speer 120gr Gold Dots trying to find the right combination. I thought it was never going to happen but ended up finding two loads that worked. Both shoot .5 MOA at 200 yards which exceeded my expectations.
I have used the 129 ABLR for several years now and did find a pet load for the 129 ABLR using AR Comp. No other powders I tried worked and they did include 8208 and CFE223. AR Comp, however was the key to making it work.
Your grouping is not that bad. What gets me worked up are flyers and your group is pretty clean. Curious what your extreme spread and standard deviation was for this load.
You may want to start looking at seating depth to see if you can tighten up the group. What worked for me was a COAL of 2.265 with OTB of 1.644. That is a 147 thousands jump, which for me, I thought that is a lot of jump but it worked. Keep working on it.
