For Years IMR 4895 was my my match powder, with 155 Sierra MK. Norma 202 was also aexcellent powder but sometimes hard to get.
H322 was also good with 150/155 grain bullets.
Benchmark or Reloader 10 today is good with 150/155 bullets.

Varget and Reloader 15 are excellent...............all around powders for the 308 win...........but some reason IMR 4895 is my powder of Choice for the 308 Win.
