My .40-65 brass is all reformed from Rem .45-70 brass.   It comes out pretty long.  Long enough that to get them to 2.113" for my first fireforming, I have to run them through my trim die and file a pile of length off of them.

I've got two .40-65's from Shiloh and the first has a slightly deeper chamber and wants the brass to be 2.105"-2.107".  The second hasn't had a chamber cast yet but seems to work quite well with 2.1" brass.

You cannot really say that except in a general way.
The data in your references are just ink on paper.
The real information is found in the actual chamber and they are practically guaranteed to be longer than all factory brass. 
You have to measure each and every chamber length to know what you have.
For example I have a Steyr manufactured rifle.
Data for the round says the case maximum is 2.110.
The rifle's chambers actually measure 2.150.
I trim cases to be fire formed to 2.150.
Dangerous you say?
Cases fired with smokeless shrink to 2.145.
Always measure your chambers...

Most chamber necks are .005 to .007 larger than loaded ammo.
If you use thicker brass and or larger bullets the chamber neck might not have enough clearance.   
However I have rifles with factory chambers that are .014 larger than loaded ammo.
You can cite all sorts of what if and theories to justify caution.
The best practice is to measure the chamber.

You can easily measure the neck diameter by flaring a case oversize.
Flare the case mouth to a trumpet shape about .030 larger than a loaded round.  Force the case into the chamber and then carefully extract.
The flare will have been compressed to fit the chamber neck.
Measure the flare with a micrometer.

To measure the chamber length start with a case that will fit the chamber but has a neck too long to fit.   
Trim the case to about .050 too long.
Flare the mouth.
Push the case into the chamber.  If it does not fit trim it .010 and try again.
Keep flaring and trying and trimming until the bolt closes.

Once your test case fits try with another .010 longer than the last pass of the first case.
Flare and trim .002 and test again until the second case just barely allows the bolt to close. Triple check with a 3rd case. When you are happy with the fit write down your chamber length and neck diameter for that rifle.
