[QUOTE="jrock, post: 933192, member: 78569"] I would recommend 400 yards minimum especially if your rounds are 3100 fps or more. Sure, it can be done at shorter ranges, heck I did a 400 yard ladder test that matched up exactly with my 100 yard single group testing. Do your final test at the distance you are shooting at. A good way to think about it is what is the MOA of your gun with you behind it? Say 1" for this example. At 400 yards your groups will be around 4". Run a ballistics program varying velocity to match your loads and look for difference in drop at 400 yards. You will see that the groups will overlap. Do you want over lapping groups? Not a bad thing if you keep track of each round or group while shooting the test. [/QUOTE]
