Mo,
I have attached the files with measurements and distance.
The photo __IMR4895-31.7gr.jpg was with 170 grain Hornady FN
The photo __VV_N120-24.5gr.jpg was with 125 grain Sierra HP FN
EDIT: These were Marlin 336W 30-30 w/20" barrel, scoped 4x32, benched, @ 100 yards
I hope these come out well. The VV pic was scanned a little crooked, but I got a good reference on the application to adjust the width of the square to be 1".
These are the correct measurements, and they are what I get when I use my calipers and calculator.
Thanks.
