They are now being marketed by Hornady.
As near as I can tell no different, save the name.

Yep, the exact same bullet comparitor stuff but now sold under the Hornady brand.

I have a complete set w/ most standard modified cases, but stopped using them years ago when I learned the stick method to find the exact C.O.L. to touch the rifling:

I don't use a stick, but use a Dewey cleaning rod guide for the particular caliber/rifle. Take off the O-rings or just turn it backwards so it will easily slide inro the chamber. Take your bullet of choice and hold it to the end w/ one wrap of masking tape. Insert into the chamber so the bullet touches the rifling and hold it in place w/ the Dewey locking collar. Insert a cleaning rod w/ a flat tip so it touches the tip of the bullet and mark the rod at the muzzle. Remove the guide/bullet and insert the bolt. Now push the rod down the bore so it touches the bolt face. Mark the rod again at the muzzle.

The measurement between the two marks is the exact C.O.L. to just touch the rifling w/ that bullet.

What do you measure between the lines with
(A YARD STICK ?)
If you want a precision measurement then do this
Take a full length sized case cut one side of neck down to the shoulder with a hack saw remove all burrs insert bullet just enough to hold it and then chamber it remove and measure over all length with calibers.
there is no guessing about this length.

The brass rod is scored w/ a razor blade and measured w/ dial calipers. Dial calipers are graduated at .001" but can be read between graduations at .0005".

Your method is the least accurate as there is nothing to hold the bullet in place but neck tension. It must be long and driven into the rifling against the neck tension which scores the ogive. It will probably pull out slightly when removed. I'd rather use a modified case and the Sinclair Tool than your method.

I do have the Sinclair tools to accurately measure at the ogive, but find the stick method to be within .001" of the Sinclair.
