The funny thing is we measure everything from top to bottom, inside and out, on and on .
As Darrin has mentioned he messed up once forgot to measure and the Damn thing shot just fine!!
We can go back and forth arguing who's right and who's wrong Blah Blah Blah forever and it really doesn't matter. Just find what works for you..
If someone ask I (prefer ) to say - this is what I do rather than you need to do it this way it's the best!!
Ok I'm Done
Have a nice day
1st time I ever sorted bullets was 300i have tried all sorts of bullet sorting and trimming and pointing
found that if i buy berger bullets not a whole lot is necessary. haven't tried any customs but i would expect them to be even better.
all i do now is quickly weigh sort looking for oddballs. not many in a box of bergers.
Interesting ,so did you shoot these in three lots ?1st time I ever sorted bullets was 300
Berger berger vld's. Hornady's comparator
Low ends were .0045 about 35 pieces
High ends were .0085 about 65 pieces
Remaining bullets .0065 right were berger lists them.
YesInteresting ,so did you shoot these in three lots ?
Ya pita for sure, hopefully it will be a hung jury.....lol. Whats the temp up in GP? 29 hereYes
I shot the shorts in initial load development with Rl26.
Today I'm gonna shoot the longs in
Secret Cackalacky load with h4831sc,
Both mag length and 2.80 seating depths.
Will fine tune the 200 .0065 length in final development.
Sorting bullets is a time consuming PITA.
This jury is still out for deliberations
Or is related to that thing in a bra n pumps27 degrees at my house, seen a guy this morning in a convertible with the top down wearing a fir hat . He musta lost a bet![]()
Apparently one point.On a separate note: I loaded up 100 rounds of Berger 140's 2 weeks ago and never checked the ogive bearing area ( it was from a different lot #) my mistake. After I loaded 85 of them I thought wow I never checked my seating depth and on a Wilson arbor press it doesn't change but guess what on this lot of bullets I was .006 off of my go to load. I ran that load on a Saturday morning in open F class and shot a 599, would all that measuring helped ..... I doubt it. Just makes you wonder how much it's worth.

Spin them 30,000 rpm held in a collet fit in a Dremel tool. Put an amp meter in the power cord. The more out of balance bullets have, the more current the tool draws.They should be sorted by jacket uniformity but the non-destructive ways of doing that require some complex electronics.

This was done at Sierra's California plant in 1971. Amazing accuracy with bullets needing minimum current.
Or find a Vern Juenke machine that senses bullet jacket imperfections.
Not me, I'm just passing on info I got from Mid Tompkins. He worked with a tool maker at Sierra's plant to spin 30 caliber Lapua D46 185 grain FMJRB match bullets.You may have found the bottom of the rabbit hole.

I think the point here is that most people sort based on what they can see or measure: weight, length, diameter, etc., when in reality, it's what you can't see (jacket concentricity) that will kill your accuracy. Particularly at long ranges.Not me, I'm just passing on info I got from Mid Tompkins. He worked with a tool maker at Sierra's plant to spin 30 caliber Lapua D46 185 grain FMJRB match bullets.
Always sort by OGIVE length and weight if you are looking for best groups,BTO base to Ogive way more important than OALOK, I just purchased a box or 500 Berger 6mm 105 Hybrids. How should I sort them - by weight, by bearing surface length, by both, does it matter?
