200 Yard Group Measurement

[Jim Hundley]

I measure my 100 yd. groups by measuring the outside edges of the group,then subtracting the bullet caliber method.Do I use the same method for 200,300,400,etc.?I have been told that at 200 a 1.00" group would be the equivelent to .500" at 100 yds.Please enlighten me on the correct process! Thank you,
Jimmy

Thanks,Abinok!
Then a 3" group at 400=1/2 @ 100?
In other words:.5 @ 100
1.00@ 200
2.00@ 300
3.00@400
6.00@500
Double the size per 100 yds.?

it goes more like this:
1 inch @ 100 yds = 1 moa
2 inches @ 200 yds = 1 moa
3 inches @ 300 yds = 1 moa
and so on

so if you shoot 1 inch at 4ooyds you are shooting .25moa, or the equivalent of .25 inch at 100 yards

Gotcha!
Thank you,
