My 500AIMM (Ultramag case cut back to 1.800) I have to do the same to get a tighter fit especially on the .500 Barnes bullets.
It does look they are sized down a good bit more than needed, but one theory might be to eliminate bullet set back if one were to hang up feeding.
the current 275gr Banes I have on hand mic .4504-.4506 at the base on the half dozen I just checked.
