    I don't know anything about your action, but if its strong, you can find another accuracy point at 46gr of H4831sc for your 140 class bullets. I use the 139 scenar for match shooting as do many others at our local range, with great accuracy. With Rem brass you can go 47 gr, velocity just over 2800 with a 26" barrel. Most of us are shooting 8 or 8.5 twist, if that matters.

    I bought 100 243 Lapua brass, but found that I can get more powder in the Rems. I have weighed several @ 159.9 to 161.0. These are the ones I have been using for my 129 SST Hornady @ 49.9 - H4831 SC. They shoot OK, but not really hole / hole at 100 yds. I have ordered some 130 Bergers, but not received them as yet. I wm also going to round up some Lapua, 139's I am going to try your recomendation. Thank you for your reply...

    just keep in mind the scenars are match bullets - don't try to hunt with them they won't expand properly....

    This load should work with your "140 Amax" but you may need to sort bullets by bearing surface for best long range accuracy.
