I like to start with groups under.5 at a hundred and make sure the velocity is where I want it. Then get all my data at 500, 800, 1000 and depending on the rifle beyond. I really like to get 5" groups at 1000 but not all guns are equal and at this moment I only have 6 rifles that I can be sure will do just that. Have several others that will do 3/4 MOA to 1000. But it's more the nut behind the trigger than the trigger most the time. 👍🏼
