    The simple solution is... BIB/Barts bullets.

    i think the consistency of the curve of the ogive has more to do with consistent seating depth than anything else that is as long as you are using a quality seater like the wilson. measuring tools and seater stems catch that ogive at different points. as long as the curve is consistent the the measurements and seating depth will be consistent.

    the higher quality the bullet the more consistent that ogive will be.

    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

    i 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.

    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.

    Yes
    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

    They should be sorted by jacket uniformity but the non-destructive ways of doing that require some complex electronics.

    How many have sorted bullet length by using a bullet seating die stem? Reason for asking is that I’ve discovered virtually consistent length on Berger 105 VLDs target bullets when using a Redding VLD seating stem where a Hornady ogive comparator was revealing several thousands of variation in a lot.

    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.

    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.

    You may have found the bottom of the rabbit hole.

    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.

    Like said before, it really comes down to what discipline of shooting, how competitive you want to be, and the lot of bullets.

    I checked BTO of a "lot of 200" - 140 LRBT's a couple nights ago, and for shooting steel, I could have gotten away with ignoring it. 90% were within .001 of each other. The last few had an extreme spread of .003. Bearing surface had the same extreme spread. Weight range went from 139.84-140.18 I would love to get another lot and see what the lot to lot consistency is. If they are always that good, I can see why ShootsDots likes them so much. That lot I feel I could pick them out of the box, and shoot them at steel and be very competitive. Though I already checked them, so I will keep them separated. If I could find more of the same lot, I would buy every last one I could afford.

    Thats less then HALF the spreads that my current lot of 105 hybrids has.

    I have a "lot of 500" - 150 smk's that sorted very, very well also. And a friend gave me 10 of a second lot that, that had significantly more variance across 10 bullets, than the lot of 500 I just picked up. Again, almost double IIRC



    A good friend of mine that doesn't sort bullets, and he shoots pretty good at 1k paper, sometimes. But the consistency isn't always there. Its all in your discipline, your lot of bullets, and how competitive you want to be.

    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.

    Always sort by OGIVE length and weight if you are looking for best groups,BTO base to Ogive way more important than OAL
