When working up a load, how many rounds do you actually chronograph per charge weight to get your AVG, ES, SD.
Been reading a lot of interesting stuff in relation to ES/SD and the statistics of how many rounds you need to fire/chronograph to have data that you can consider dependable. But my question was more, what are we actually doing right in practice, not theory. I allowed 2 choices so that if people have different standard for pistol or rifle, or training vs precisions ammo and you have different methods you can list both.
For general purpose training loads and handgun loads I am generally shooting 10, for my precision/target ammo I am shooting 30.
