338 Lapua Ackley Improved Load Help
I will be converting my 338LM to a Ackley Improved 40 degree shoulder. The barrel is a Lilja, 30" 1-10 Twist, #8 Contour. I think that H1000 or Retumbo are good choices but would like to hear what you gents have to say. Plan on sticking with the 300 smk's.
Need info like, Primers, Charge weight, how far off the lands, etc. Thanks in advance.
