ND, just load that bi-pod either to you or away until you find what the rifle likes, and on the other hand like Dan mentioned that ammo isn't know to be the most accurate, and 1.75 inches at 25 yds seems to me the rifle doesn't like the ammo, so switch to something else.
My .270 win loves 130n grain pills so much it's hard to get excited about testing heavier bullets through it, but I got some 140 grain Partitions to load and test, hell it might like them even better!
And the last thing I can think of besides shooting skills is the scope and it's mounts, the integrity of these three things come into question when the groups are that wide.
