[QUOTE="rscott5028, post: 645357, member: 24624"] Assuming you are referring to group size, and further assuming that BR shooters are the most precise shooters of all, I'm still not willing to stipulate that smaller groups imply one method is more centered in the chamber. How did your BR friends measure centering in the chamber? Likewise, the popularity of one vs the other for any given shooting discipline isn't proof positive of centering or group size. There are many pros and cons to both methods. Nonetheless, it was a seasoned benchrest shooter that got me to change over to FL sizing for my 6br. So, I'm not even certain that your ascertion that most BR shooters prefer to neck size is necessarily correct. I do however agree that "physics apply to any rifle." I would add that physics applies to bullets as well. I'm just not sure what it has to do with centering in the chamber. Then again, I'm not sure exactly how much runout it takes to reduce accuracy; nor what that little ejector plunger off to the side of the boltface does to help center a round precisely; nor if we're talking about once fired/neck sized vs 5 times fired/neck sized and almost unable to close the bolt. Is the case and/or the bullet getting more centered each firing? Do your groups just keep getting tighter? When you finally decide to bump your shoulder, does your precision shooting suddenly fall apart? -- richard [/QUOTE]
