Thx guys. Still not seeing how a finish reamer could work correctly after a pre drill since the pilot won’t be following the bore in the beginning. Seems it would have to be very rigid or it would wobble
They do not and can not cut past the very tip as the are cylindrical ground ...
I assume you are talking about ordinary reamers (like chucking reamers, hand reamers, et cetera) here, not chamber reamers. Virtually all chamber reamers have some degree of taper in the body and do cut for the whole length, although most of the material is removed by the edge at the shoulder in bottleneck cartridges.
That's because they are properly called "form cutters", not reamers. Not much different at all from port tools or for that matter a countersink.
That would not be the "proper term" in barrel chambering discussions among practitioners.
They don't use proper terms. Proper terms are too mundane. They have to make up new Buck Rogers sounding names and buy every trendy gemcrack. We use to have a guy here who cut thru the BS, Speerchucker. He could chamber a barrel while most were selecting what black magic playtoys to use. Unfortunately he got sick of the BS.

That’s the point though, you can’t have the pilot engaged for the first part of the chamber if you predrill. It has nothing keeping it centered
