What do you feel is the largest return on investment for reducing ES ?
Neck tension adjustment?
Bullet pull?
Powder Charge?
Primer selection?
Case selection?
Headspace via Fls? Ie not the one between my ears
Late into this subject, but will add my thoughts, not on technical aspects, but on your own attitude to improving, continual improvement, or maintaining the status quo and maybe "moving with the herd" mentality.
There has been many people add some immensely valuable information in the posts above, from personal experience , and from reading and gleaning information from books, forums, and techical papers. Actual experience from those that have tested different changes is invaluable, IF you can objectively determine the outcomes of your experimentation are due to the inputs that you changed (for example, was the vertical variance on the target a result of different primers, shooter error, or mirage/lighting inconsistencies).
This game, once we are past the initial learning curve, is a game of the one percenters. That is, many of the improvements that we can do to our reloading, or shooting technique, and our gear setup will only improve a small amount for each change. Many of the changes will
on their own be lost in the noise of wind reading, atmospheric changes, and shooter error on the day of actual shooting.
Reducing SD as per the OP, is just one of those changes, remembering that reducing the SD on an inacurate load does not make it better - you need a good load, then reduce SD, and make sure it replicates the results on the target
What we need to do to improve pur own shooting, is to work out what makes a difference, what has no impact, and add all of those 1% improvements together. Make sure that you pay attention to the parts of your setup, reloading, and technique that actually make a difference, and dont waste time on things that dont improve accuracy. I will plagiarize a phrase from Ben Hunt Davis, the british rower. Will it make me shoot better? Watch the video below, its from a different sport entirely, has been adapted to business sucess, but i cant think of a better way to describe how to improve your shooting.
Practice and critically review your technique, test different reloading/brass prep, etc, but work out if it makes you shoot better. If it does improve your shooting, and only a needs a small amount, do it. If it makes no difference, dont do it. "Will it make me shoot better?"
BTW, those of you that spend the time to test different things in shooting, to deterime if it makes a difference, are generally those that sit at the top of the leaderboard. Those that follow others believing that it makes a difference will generally lag behind and take the minor places.
Well worth watching the below video, for personal, business and how it can relate to your aporoach to shooting.

Will It Make Me Shoot Better?
Test things, test things often, and only do what makes a positive improvement.
