That one above is a PTG reamer print specifically for Midway, and says "bolt gun only". It has a tighter .294" neck, but it does have the compound throat if you look at it.
SAAMI chamber has a .300" neck and compound throat. You can see the compound throat with the freebore starting at .2644", then goes down to .2617" before the conventional angle into the rifling.
I personally wouldn't want a .294" neck in a gas gun for 6.5mm. My .260 Rem gas gun has a tight neck, so I have to size all my brass before I even load it up, even new Lapua cases, which takes more time and effort to load.
