Couple threads have had bullet sorting pop up recently. I had some ELD-X that I wanted to sort to see how consistent they were. So, decided to compare the 143 ELD-X to some old 140 Amaxs, I have.

In the results below. I weight sorted the 143 ELD-X into .2 Gr groups and sorted those groups by Base To Ojive (BTO) groups of .001

I then weight sorted the 140 Amaxes into .1 Gr. Groups and sorted those groups by Bearing Surface (BS) groups of .001

Things learned:

1) Discovered that BTO and BS correlate to the bullets weight! This means that bullets only need to be sorted by one method or the other and the results will be about the same. Not exact, but very close.

2) BS sorting is easier than BTO sorting. BS sorting with a pair of Hornady comparators on a caliper is much easier and more accurate than BS sorting using only one comparator.

BTO and BS also correlate to each other.

3) ELD-X tolerances are held no where close to Amax tolerances! I assume this is true with ELD-X vs ELD-M too.

4) Last, if all of this gives you a headache, Just shoot Bergers cause their tolerances are way better than Hornady's.

Numbers and how I finally grouped them for my use are below:

Weight 143.1 to 143.2 = Count 42

BTO .787 = 27

BTO .788 = 12

BTO .789 = 3

Weight 143.3 to 143.4 = Count 35

BTO .787 = 6

BTO .788 = 23

BTO .789 = 5

BTO .790 = 1

Weight 143.5 to 143.6 = Count 20

BTO .788 = 7

BTO .789 = 10

BTO .790 = 3

My Grouping by Weight:
