The load so far is the Sierra 150 spt, varget powder.... 40 something (memory is fading), r-P brass , WLR primers. If you got a Nolser manual, look under the 150 BT, 308 page. For the varget powder, it the lowest of the three, most accurate for them. I think it may be 44 grs, not 100% sure. I'll check at home and get the exact powder charge and length and let you know.
