I was having a few concerns about my DMR3 tracking, so I shot a tracking test. I shot 40 rounds total alternating shots between 0,5, and 9 mils all holding at the bottom dot of the target. Initially I started with 0 and 9 mils and then added 5 mils later on in the string of 40 rounds so that is why the 5 mil group has a few less hits. This was done at 100 yards with a 6.5 creedmoor. I have not measured the target yet but according to the retical it tracked very close to the dials.
