The loads I have been shooting are .033 of the lands. I would feel more comfortable moving a little closer with each test load and not less that about .010. Is moving closer each test load .005 till Im about .010 off the lands a good test interval? If I do that it would be 6 different loads to test. Is that best or spread the interval out and have fewer test loads at first and use the data to make a second round of testing?
