Only way to know is to buy a box of near everything, and send them down the barrel. Each rifle is unique, and no two are alike, even coming back to back off the same assembly line. There are so many variables to bullet path. If the rifling is just a little smoother than the others, or , for example, there is a little tool mark in the barrel, or the crown took a nick during shipping, that even though they are identical rifles, the path the bullet takes will be vastly different.
What works for one gun will be nearly pure coincidence to work equally well in another of the same make. I have tested this theory with about 8 different rifles over the years. And not a single one shot the same with the same ammo. 2 times, there were actually VAST differences in the point of impact between 2 same guns. (I have had many occasions to shoot doubles of rifles as a lot of my friends "copy" my buying patterns it seems )
