Re: 195hornady match, .308
Not for 195 gr but I do have a load using the 2000MR & either Berger or Lapua 185s w/ Lapua brass. Start at 46.0gr . Alliant site posts a Max of 46 something for a 185 SP. I found in my 26" tube that I get to 600 using almost 4-5 MOA (depending on temp).
Hope that gives you a starting point.
