I'm not that far down the line.
I've got my clicks from Chairgun and checked them at 10, 25 and 55 yards, they were spot on.
I checked the distances on our measured lane, and kept finding the gap between 40-45 a couple of mm less than the 45-50.
It's the 40 yard distance that doesn't seem to fit the curve, and I checked it a couple of times and it repeated OK.
I was just wondering if my assumption that the distances would reduce evenly was correct.
If it is, I was obviously mis-ranging the 40 yarder.
