Thanks in advance

SAAMI (C)OAL is from 2.54" to 2.71"
There is no such thing as a standardized CBTO length since there is no standard reference point on the ogive.

Thanks, I have the SAAMI and the CIP (for Europe) standards, I was looking to build a database of the measurements of factory loads.
Sorry my terminology may be wrong, CBTO - cartridge base is self explanatory, Ogive the point where the bullet contacts the lands?? Can be measured using a bullet comparator.

I didn't think this was a contest to win or loose. I don't know about C.I.P, but we don't have or use figures like the ones you are asking. To get the data you are asking for in the US ammunition market would take months and thousands ( and more thousands) of measurements for numbers that do not have standards over here... we just don't care about that measurement.

Too bad you had to experience Catshooter personally.
He is considered some what of a Git and his primary contribution to a thread is controversy.

To bad you didn't have anything to offer that was better than your usual snide and ignorant remarks.
I tried to help several times, three other guys tried to help him. "Mr. Essex" got rude and testy...
... you added nothing (as usual).
