Can someone recommend a temp controlled powder(s) for the Berger 130gr AR Hybrids? I am using 8208XBR for 130gr TGK.

I worked with the Berger 130 Hybrids quite a bit. Here is some data for you for H4895 and Varget.
All numbers generated from a Ruger American Predator, 22" barrel. Shot in April this year at 62F / Avg of 5 shots.
No airborne Covid19 particulates noted)
H4895
26.6gr = 2254fps / SD=6.1 (<1 MOA)
26.8gr = 2262fps / SD=6.8 (1 MOA)
27.0gr = 2275fps / SD=12.2 (+1 MOA)
27.2gr = 2330fps / SD=9.7 (<1 MOA) Spike! No pressure signs
27.4gr = 2344fps / SD=6.8 (1.5 MOA) Some Cratering
Second Outing Doing 27.1 and 27.2 of H4895 (73F/Winds Calm)
27.1gr = 2295fps / SD=6.5 (0.5" MOA) case length=1.520" / OAL = 2.255"
27.2gr = 2320fps / SD=12.6 (+1 MOA)
27.3gr = 2340fps / SD=10.8 (1.2" @ 100 BUT...........0.70" @ 200 yds)
Next is Varget Shot same as immediately above:
26.6gr = 2204fps / SD=13.9 (Most Accurate at 0.73"MOA)
26.8gr = 2218fps / SD=6.8 (3 inside a half inch and two AWOL's)
27.0gr = 2233fps / Sd=8.5 (Right at MOA)
27.2gr = 2267fps / SD=13.8 (little over MOA)
27.4gr = 2274fps / SD=9.3 (Vertical Stringing)
And for S*#ts and Giggles:
Shooters World tactical Rifle Powder:
27.4gr = 2347fps / SD=14.2 (Really Crappy)
27.6gr = 2368fps / SD=10.3 (better but over 1 MOA)
27.8gr = 2386fps / SD=9.7 (hair under MOA, 5th shot moved).
28.0gr = 2463fps / SD=9.1 (SPIKE!!!!! Crappy) Cratering and *stiff ejection
*Not that kind of stiff inje............never mind!

I think you re-posted your H4895 powder weights for your VARGET weights.
They are the same numbers and about 2 grains over book max.
