For my 1/2 MOA prairie dog load...50 gr V-Max (actually Z-Max...I bought a 10 year supply when they were being closed out.). I like cheap and small groups. A tenth above published of CFE 223 works in my heavy ARs and Savage 12 FVs.

What ever your barrel likes. a 1:9 twist should stabilize a 69gr bullet without any problem. I have several 1:9 twist AR's and each one prefers something else. One will shoot the lighter bullets accurately while both like the heavier pills. The chamber and leads have a lot to do with this. Those will long leads do better with the heavier bullets.

1:9 is a lot more versatile than 1:7... you are able to successfully use lighter bullet weights.
I've had more than a few AR's over the years, Blue is correct... it seems like each barrel, even barrels with the same twist, like different stuff. I think a lot of that has to do with barrel rigidity, material stock, and the quality of manufacturing.
If accuracy is your only requirement, I would pick a quality match bullet of appropriate weight and work on it.

If your gun doesn't shoot a 69 grain sierra matchking it's time for a new barrel.

Something I found when I was assembling the last 2 AR-10's... is lapping the receiver for the barrel, to true it up. Barrels and bullets are one thing, but helping the rifle do all it can is another aspect.

I agree with the 69MK recommendation, I've also had great luck with the 69 TMK.
But, what's your purpose??
the 69 OTM and TMK shoot extremely well in my 1:9" barreled .223s, but I've seen OTMs fail miserably on coyotes. For that application I've had great luck accuracy wise and terminal with 55 BTs.

I don’t have a purpose yet. I have a cool looking A2 style rifle with a old school carry handle and want to learn how to use the sights. But I want it to be effective if SHTF happens.
What’s the purpose, for now... Grand National Match gun... or pretend at least

I think I have those! I have 3 AR’s 7.5 1:7, 10.5 1:7 and 20 1:9
I was thinking one of those will like a load
