Hello again. I have been researching scopes for small bore silhouette. Based on advice from fellow members, one scope I am looking at is the Nikon Buckmaster 4.5-14x40 SF w/Mil Dot. I was advised to check out the Nikon spot on software, very nice by the way. I was curious as to what would be more accurate - dialing elevation or mil-dot hold-over. I chose a generic 40gr 22lr with standard velocity. The software indicates that the third mil dot - 139 yards, the fourth mil dot - 159 yards. This scope mils at 12x, I verified that 1 mil equals 3.6" at 12x. Here is the issue, using the same software - it states that the 140 yard drop would be 17.37" which equals 12.49" at 100 yards or 11.98 MOA. When I convert that to mils it equals 3.43 mils, but the chart indicates a 3 mil holdover. The fourth mil dot - 159 yards, I checked this as well. The 160 yard drop would be 26.36" which equals 16.57" at 100 yards or 15.89 MOA. When I convert that to mils it equals 4.62 mils, but the chart indicates a 4 mil holdover. 4/10 mil and 6/10 mil differences are pretty large, it seems to me that dialing elevation is much more accurate assuming proper tracking and repeatabilty. By the way, the softwares MOA come-up figures closely matched mine. The 140 yard come-up in MOA is 11.8, I figured 11.98, the 160 yard come-up in MOA is 15.7, I figured 15.89. With all the variables the same - 70 yard zero, same cartridge, same program, etc. it seems mil dot holdover is not reliable; can mil dot holdover be accurate? I do realize that both methods have to be verified at the range.
