I'm a scientist and a novice shooter, this series of articles make a lot of sense to the scientist in me. But the novice likes to listen to as many points of view as possible....so yeah hence the questions.

Im not after what the "actual statistical accuracy" of the load is. I was after 'some' amount of improvement in group size over what the last of my load batch was now shooting.
I shot 4 similar looking groups after checking new powder lot, bullet lot and also checking zero after falling with the rifle after a weekend of hunting . They all shot similar shaped and sized groups. After changing seating depth you can see two obviously better groups.
Now after loading up a batch at that longest seating depth I will find out if it stays 0.5moa or better. If I find it trends to be the same as the last lots at approx 0.7moa then I'll be pissed at my hard work & time wasted , but it will still be more than accurate enough for my hunting needs
