Ya gotta test for yourself to get the good loads.
You might be on the right path with the 125gr's but maybe playing with powder type, and seating depth will sort it out.
Try asking in the reloading advice sub-forum.
I don't have and AR10 or a .308.
I HAVE loaded 120gr powder coated bullets in .30-06 and .30-30. Ladder tested and found very accurate, mid range loadings.
.30-06 @ 2550 fps
.30-30 @ 2300 fps
Both have light recoil and have worked very well on deer.
I like cup and core bullets in 30 caliber and larger. Cheap and do the job.
I've used it regularly with Berry's 123 grain plated bullets, but unfortunately the combination probably lacks the port pressure necessary to reliably cycle any gas operated .308/7.62 NATO autoloading rifle.
BTW, the Japanese and Spanish both fielded reduced-power 7.62 NATO ammunition at different times. The JDSF has/had a alternative 7.62 purple/violet-tipped load intended to make fully automatic fire from their Howa Type 64 assault rifle somewhat more controllable. https://www.forgottenweapons.com/rifles/howa-type-64/ I don't have completely trustworthy figures on the ballistics for this load, but here's a supposed photo of the bullet (center):
The Spanish originally standardized on the 7.62 CETME loading of a 113 grain bullet at around 2600 fps for their early production roller-delayed rifle. This ammunition was produced in large quantity until withdrawn in the mid-1960s in favor of NATO-standard loadings.
There is also a 130 grain load in US service (T762TNB1), but at 2900+ fps I don't think you could classify it as reduced power.
I find .308 favors middleweight to heavy bullets (147 grain and up) at 2400-2650 fps better than lighter bullets. When I had my bolt gun .308, it shot well with 155's, 168's and 178's. My M1A does best with 168's. I generally use 125's in smaller-case .30 cal like .300 BLK.
Hodgdon has reduced loads for .308 factory, Hornady custom lite loads are nice too, cycling the ar10 should be the bigger challenge rather than accuracy. I love producers, also consider the .30-30 and .300 savage specific bullets at reduced speeds, just a thought.
If you want something really fun, try 110 Hornady VMAX’s. Recoil is between a .223 and .243. At 3,100 FPS they are like lasers. Note however that this was a 1:12 twist barrel. I tried them in a 1:10 twist 30-06 and a 1/3 of them would blow up at 50 yards in a puff of lead dust
I love those 110 V-Max. Load them in .30 Carbine, .30-30, .30-06. Keeping them below 2800 fps in '06 and .30-30, they are grenades on yotes.
.30C is not near that fast, but they are fun. Acting more like a typical ballistic tips bullet, mushrooming perfectly on 80# hogs.
I'm super interested in the .30 Carbine loading. Do you have any pics of the fired bullet and the wounds? Distances fired? Shot placement? How far did they run?
No pics. They were on my old phone.
Distances were 10 - 50 yards. Chest shots, heart, lung, liver. 50 yard shots, ran about 20 yards. 10 yards shots, full penetration, exit about quarter size, spun around and fell.
I wouldn't use them on deer. I don't use .357 on deer, either.
I have used these in 30-06 with decent results, at least on paper. They are about 1-1.25 MOA with H4895. Nice soft shooting load.
