Re: .308 accuracy load for 135 SMK
Both the Sierra and Berger 135's are good bullets, but I am surprised they shoot so well for you in a fast twist. I have shot both in my 30BR with 18 twist - however I find the lighter 110-118 gr. bullets are more accurate for my 500 meter groundhog shoots. Varget should be the powder of choice in your .308. Have you tried RL 15 or IMR 4895? Another good bullet in my 30BR is the Speer 125 grain; very accurate.
