.20 Tactical Load Data

My AR .20 Tactical build is just about complete. I have on hand Laupa .20 Tactical brass and Federal 205MAR primers. The barrel is 1:11 twist and I would like to hear what powder and bullet combination you have had the best accuracy with.
Thanks, TimP
 
25.8gr/Benchmark powder, 40gr Berger bullets and CCI450 primers. Lapua DAK TAC20 brass. Necks .010". Nesika "T" action, 26" Pacnor SSSM Bbl, 1/12" twist, #3 contour. 3915fps over an Oehler 35P chrono. Expect 1.5" groups, or less @ 250yds This IS my coyote rifle.
 
Mine is a .20 Practical, so it's close. 32gr Blitzking or 35gr Berger and 24.5gr of N133.

The grid in the attachment is 1/4" and it was at 100 yds.

I've found a lot of variance in lots of Benchmark,s the stuff I've shot wont yield the velocity. I've attained 3900fps+ with 40 vmax and N133 and R10X, the later far less expensive.
 
H4198 and 39gr BKs were unbeatable in my 20 Practical. You might look over on saubier.com as well, lots of small caliber info over there.
 
My AR likes 21.5 grains H4198 behind 35 grain Berger bullets. 1/4" groups @100 yards. (Noveske barrel).
