Brass sorting

[Jcalder]

For those of you that sort your brass, what's the tolerance you use. Processing some brass, and have a scale on the way, wanting to batch them out when the time comes. Not sure it matters, but wanting to try it

I use +/- 1.5 grains on the Creedmoor cases.

My BIL sorts bullets and brass into weight categories using very small increments.

If you are shooting dots at 200 yards like Mr. Big, these kinds of variables matter.

I tried this with my hunting rounds and frankly the different results could hardly be quantified.

If you are looking to maximize accuracy then I would look to
1. uniform your primer pocket and flash hole
2. annealing case necks to obtain uniform neck tension
3. determining the case capacity and setting aside outliers.
4. Determine the exact jump in your rifle and achieving that on every round.

Your objective is to achieve uniform powder combustion and expulsion of the bullet into the bore.

I found jump to be near as important as powder type and charge weight.

I will be the skeptic on this one. I think it would be more important to sort the brass based on its capacity rather than the weight. What if the extra weight is on the outside dimensions of the brass? If you turn necks you remove weight from the outside of the case. Sorting by water capacity would give you an internal measurement of the brass that might be more helpful.

Much appreciated. Think I'll approach this differently
