At 600 yards we use a 3 inch spotter disc that is put in your last bullet hole, while the previous is taped shut. Target comes up and you can see your very last shot location....
ANyway I've almost never shot anything but the AR15 with iron sights in service rifle, in a jacket prone with a sling all the way to 1000 yards.
I have a spotter disc somewhere from Camp PErry from a 20 shot 600 yard match no sighters, that my pit crew gave me when we swapped relays... had 17 .224 cal holes in the 3 inch disc....
And I've shot a lot of groups that were 5 shot groups off a bench with irons testing different components at 600 yards. Almsot all have been 3-5 inch groups with the right ammo.
Seventeen shots and you didn't hit the spindle... Dood?
That's some awesome shooting Jeff!!!
