Is it the condition of the case?
Is it the bullet used?
Is it the powder?
Or COAL?
Based on what you actually asked, here are my meager thoughts:
1. Bullets - you can do everything else absolutely perfect, but if the barrel simply doesn't like the projectiles, you won't get good groups. Simple as that.
2. Powder selection and charge weight - consistency is really the key here, and I do not believe that it needs to be at a .02 grain accuracy level on the charge weight to get near identical performance. Some will argue that it does. Powder selection is also important, more because you need a rifle powder for a rifle load (safety), but some guns will prefer a type of powder over another.
(Not Listed) - Primers - the right type of primer for the powder can make a difference.
3. OAL - with the exception of specific types of bullets (VLD's, for example), really kind of overrated. Most shooters won't be able to tell the difference between .003" off the lands or .10" off the lands (assuming every other aspect is the same between rounds). The biggest factor is consistency between rounds.
4. Case prep - largely overrated metric. Some swear that you need to do X or Y or Z method of case prep to get acceptable accuracy, but it has been proven more times over than not that X or Y or Z aren't required (I still trim, chamfer, debur, neck turn and a few others personally because I like consistency). Will doing so make a difference? Sure it will, but I'd bet that you'd be hard pressed to find measurable differences between rounds that have perfectly prepped brass versus so-so prepped brass out of the vast majority of rifles.
The rest of the thread is opinion on a whole lot of other things, and basically arguments on the same thing from different angles and people justifying why the do X, Y or Z to their reloads. Yes, all of them will make some difference, but the degree of difference is significant between them.
