Mike,With your tuner and rifle, what is the interval between settings that give perfect tune, and what does that represent in terms of movement along the barrel axis, in thousandths of an inch?
Boyd, it's not 100% linear but is close enough to get a good average. Some vibrational nodes are narrower than others, like blips on the oscilloscop. Average between nodes is 8 marks on a typical short range contour cf barrel and my tuner. Each mark is essentially equivilent to .001" of tuner travel. The distance between in and back in is not as important to know as the range from in to out and makes it at least twice as complicated as it has to be. The trick is to find your range between in and out of tune and work within that small window of about half as far as in to in. Clear as mud?
