Dots are .06 mil, main stadia is .07, windage stadia left and right of center are .05 and vertical tick marks on those lines are .04. The smaller dots at the .5 mil marks in the grid are .028 mil.
Thanks Jerry. It's interesting why the H37 has thicker stadia than the H58 since the H37 is intended for ultra long range. Do you have any experiences of it covering up the target at longer ranges?
It is for ultra long range but also consider it has been around for quite a few years now. I have had a couple issues with coverage on smaller targets at greater distances but only when holding no wind, which isn't that often. I have recently pulled the 37 and replaced it with a 59. A couple of my other 5-25's have 58's and they work great for me. I never really found the additional 4 mil of holdover or the additional wind holds a big enough advantage or necessity to feel that I needed it over the 58 or 59.
For rifles that need the additional windage or elevation correction it could play out completely different and may work even better.
