Check your neck tension. Variations in neck tension can effect seating depths. A hydro-seater can be used after an expander mandrel to uniform seating pressures; If .308 bullet, use .307 expander mandrel before dropping powder. Control the ID. You've already squeezed down the OD when sizing. Each piece of brass may have slightly different neck wall thicknesses. By using the expander mandrel, you are uniforming the "grip" on the bullet.
I have tried to sort bullets like you did and I could not trust the readings because it could change just how the bullet sat in the holder. I would think I had a bunch of + bullets and go back through them and find many were not + bullets. You demonstrated that with one of yours. There just has to be a better way!
My question goes like this let's say we're going to measure the length of a bullets bearing surface, a flat base bullet is pretty visual, but a boattail designed bullet is going to be more difficult to envision. Or how about a boattail designed bullet being seen from both the length of the bearing surface and the length of the tail.
What type of bullet seater do you use? I have a Wilson seater that I use with a harbor press and I can’t get consistent seating depths. Right now I’m using Berger VLD because I can’t get the Berger Hybrid,s I’m thinking trimming and tipping might help.
You're dealing with variations of 0.001 inch or less. How certain are you that these are due to bullet length, and not to irregularities in the ogive or failure to seat the bullet exactly vertically in the gauge? What are the accuracy and precision limits of the gauge itself?
There are a lot variables. The goal is to get as uniform as possible. Are they going to be perfect? Of course not but they will be very close and how close is dependent on everything you have brought up. I often double check as well to see if there is repeatability in my measurements. The biggest thing is to find those outliers, the ones that are 5 or more thousandths off. Depending on the brand of bullet, there may be many and those are the ones I am trying to find.

8 months since your last video?
Don't leave us hanging!

Nice video, thanks for sharing.
Thanks for watching! Working on more of them.

What unit are you using to measure bullet lengths like the stand appears to be rigid

I also use a Wilson with a VLD seating stem. Are you measuring OAL or Base to Ogive?
Get the RCBS match bullet seater. No regrets
I tell guys at our range to spend less time on the arrow and more time on the Indian :)
Are you going to trim the base of the bullets to make them the same like you did in your other oal trim video?
don't you mean trim the bullet tip ? i sort by bullet weight then like he does . and finish up trimming the meplat . i dont tip , yet any way .
I’m in vermont where in up state Ny is your shop?
I'm about 25 miles NW of Syracuse
