The twist rate was wrong to begin with so anything over 55 was not stabilized, at 25 yds!
and some of the 55's looked to have had some wobble to them as well.
I sent it back and recieved one from the same batch that Oden describes above, so it seems as if the problem has been rectified. You also have to keep in mind these are not made by Dlask, the problem was with their supplier.
I am going to shoot mine Saturday and will post results.
