Shot that 47grs of 2000MR today at 600yds, my H-S stock did not fit my bag like it used to, like it lost some weight or something, anyways, it was loose in my front rest bag, but I shot the group nonetheless and the group strung horizontally, Im blaming that on the front rest bag, fwiw, the vertical was very flat from what I remember. The next load with 46.5grs CFE went 5" but I filled in the loose bag with a rag, it worked much better that way.
