I am new here and wanted to start an up to date talk about the different barrels and any load development for the lmt308mws. LMT advises 130gr. For .260 rem, 168 for .308, and 185 for .338 federal. LMT is offering a .338 fed 20 inch barrel for only $275.00 so I couldnt resis . I have been watching this forum for some time, and have seen how you treat greenhorns gently, yet not suffer fools gladly. I hope to someday enter MY LMT in some rifle matches and am interested in ranges of 200 to 600 yard ranges ,I think. Having been a garand man all of my life, till recently, I now believe that the ar 10 is ready to compete against bolt guns and win.
