I wasn't sure if you were asking just about bergers or any 20 cal pill. My favorite load is 23.5 grains of H4198 and a 32 grain Hirnady V-Max. I can shoot three of them into one ragged hole. I use IMI brass exclusively. This particular rifle has a Lilja 1:12 twist.
I don't know if you've seen this article, but there are some good Tac-20 loads in the Tac-20 section near the end of the article:
Let me know if you have any further questions.

40 Grain Berger BT Varmint Match bullets (lot 1342) seated
to 2.270 OAL using Dakota Lapua brass with CCI 450 primers.
Bullets & cases weight sorted, powder thrown from Harrels
24.8 grains N-133 5 shot 3 group agg = .309 smallest = .140
25.0 grains N-133 5 shot 3 group agg = .548 smallest = .482
25.2 grains N-133 5 shot 3 group agg = .641 smallest = .458
Same as above except using 24.8 grains of Benchmark, all components but primers
weight matched. I measured the raw group anywhere from
.417 to .419 at 200 yards
Looks like slew & I found a similiar sweet spot for respective rifles with N-133, he at 24.2, mine at 24.8, I have a 1/12 Shilen select and used CCI 450's.
Reduce your starters to be safe!!!!
PS I am working with 10X now also,.... too early to report however.

My favorite load for my boltgun Tac .20 is 32 gr V-max with 25.5 gr Re 10X lit by CCI BR4s. Bergers may shoot better in it but V-maxes are cheaper for PDs. My .20 PPC likes 40 gr Bergers best with VV N-133. I shoot 32 gr. V-maxes over 27 gr. TAC in my Ar-15 Tac .20
