Has any one duplicated 300 WSM 165 BT data with H380?

The Nosler data says H380 with the 165/168 gr bullets is the most accurate powder tested. Has any followed suit and if so what was your results?

Never used it with the 165 BT, but I have used it with the 165 CTFS. Sub-MOA and excellent velocities in this instance. Sixty-four grains of H380 yields velocity of 3067 +/- 12. Sixty-two grains gave the best accuracy--velocity was still 2986 +/- 8.

Dr. Mike,

Which primer?

Norma brass, WLRM primer, 64 grains H380, 165 grain CT Fail Safe, 0.010 inches off the lands.
 
I wish I could seat the BT even .040" off the lands since it gives the best grouping but the darn Tikka T3 mag makes me seat them about .120" off.
