CBTO

I was like joking.

thought you might have been, but wasn't sure

Here is my take on it now that we have established that the ogive is not a finite point location of a bullet. Sliding something onto the nose or ogive of the bullet hoping that it will stop at a point of consistency better than inconsistent meplats of many bullets has turned into a marketing gimmick that misleads shooters into thinking they can use this info to chamber a rifle to exact specifications. Then marketed as a must have tool for the loading bench that most people have no use for.

But "for each individual bullet" it can be used as a reference point to establish a seating depth, am I correct?

L.Sherm the Whidden bushings are more accurate than the Hornady's?

While this all may be true you still need a point of reference to load to and CBTO is the only point of reference I can think of!

I never said whidden bushings were more accurate than hornandy. What I said was I use the Whidden tool with bushings instead of the Hornandy inserts.
I wanna measure closer to were I figure the bullet is gonna engage the groves of a barrel.
Eric Cortina probably explains it better than I can why he uses a bushing the same size as the groove of a barrel he uses.
As far as bushings go I trust none of them untill I measure them with a deltronice pin

Got it!
I mis understood your comment and thanks for the explanation.

 

[L.Sherm]

I feel the closer you get to measuring were the bearing surface junction with ogive starts theres less variance, and of course manufacturers are not all the same in consistency either.

 

[Old Rooster]

I have always wondered why some were less expensive as others.
Whidden products are second to none.

Yes sir, its slick. I also use a dedicated digital caliper that is only used with it to, nothing else.

 

[Old Rooster]

I'll be ordering mine soon.The Guage first and one bushing.
One caliber at a time though

FWIW, with Hammers, I have never measured the CBTO as the uniformity from tip to tip is so good...

What the heck is an OGIVE

You left out Hammer.
I use a Hammer to make all my bullets the same length.
