Which is precisely why I write my disclaimer. Can you comment on my observations of metplat, forgive me -- ogive, shape and proximity to the lands? Do you concur or disagree?

I agree completely. Nothing is set it and forget it within the reloading game. Even using the same lot, same box of bullets I will check from one reloading session to the next. Things change, the die may be screwed in less or more, you could have bumped a seating micrometer putting the die away, or you may have changed lots of bullets and they measure a bit different. Always checking is part of the consistency game we play.

Well, not every member here shoots or hunts "LONG RANGE" as you stated. The info here can be applied to loading and shooting no matter what range the shooter uses. 406muley

15 thousands lot to lot I'll take that for the consistency Berger has with in the same lot. I buy mine by the 500 just for this reason
if you READ his post, you will see that is just not true.
and there is a reason it say 'LONG RANGE"

I still check, assume nothing. Worst case is to have a digital set of calipers, set a zero, and sort lengths...easy and quick.
It is not unusual for a throat to like .003 jump or a .003 jam...depends on how anal you are on maxing out the accuracy on that particular barrel or calling, "good enough."

I discovered this long before anyone was hunting with Bergers.
Back when Stevens bought the major stake in Nosler bullets and all that was available for long range was Ballistic Tips. I would buy 5-10 boxes of 100 at a time. This is when the boxes had those crimped in metal corner protectors.
Anyway, I had just opened a new box and proceeded to load up with the 200gr BT in my 300WM. Didn't check anything other the COL.
Get out to my usual 500mtr spot, wasn't long before a deer was seen and a round was ATTEMPTED to chamber when it was discovered the bolt wouldn't close...needless to say, not only did I not get any venison but I had a live round stuck in the rifle to boot.
Once home and the rifle cleared, looking at the ogive something was off. I had a few unopened boxes to compare and, that particular box had a waaay different ogive AND the overall length of the SAME bullet was .080" longer!
So, it's not just Berger, Hornady or any other brand, it's US that have to be more diligent in our handloading.
Cheers.

Anyone take one of each bullet and seat them without changing the seatting on the die, then measure the cbto?
Your seating die is pressing somewhere on the nose of the bullet between the ogive and tip. Bullets are being measured from the base to ogive, none of which related to where the seating die contacts the bullet. Which is what would change the ogive/lands relationship.

it is reference math
it does not matter that the seating die is touching just above the throat ogive number on the bullet..as long as it is not seating based on the tip.
it does not matter that the measuring tool is at 300 or 304 or 306...as long as the tool remains the same.
it is not a true measurement, it is a REFERENCE measurement. a number that can be duplicated in loading. one that can be adjusted in and out to change the jump or jam.

You are absolutely right! Key word for certain is complacent, as you stated. I loaded tonight and measured and remeasured every round. Part of that is to ensure I understand better the process each time I load being new to reloading. But, complacency does injur and kill. I would rather be slow and methodical, checking and rechecking than have a trip to the ER or worse... Regards, Victoria

This is true.
And jumping from one lot to another in any manufacturer, with any component for that matter, should trigger you to reassess. Not just bullets and Berger.

That is exactly right, it is a refernece measurement that in no way related to the ogive-lands (seating depth).
Yes bullets should be sorted by bearing surface length, but what I am asking is has someone taken two bullets that have a say .010" difference in base to ogive, or the same difference in bearing surface length and seated them both with the same die set the same way and measured the difference in the ogive-lands as the op referenced.
