I agree with Brian , .005 off the lands may not be optimum. You will get variations in searing depth where some bullets may be touching the lands and some may not be either .010 into our away from is a better metric.
As others have said, unless you were consistently getting 1/4 groups and now they are dble that, I don't think there is a statistical difference.
