Newbie rifle reloading question.

Just got two of them in the mail from Dillon. One in .30-06 Springfield and the other in .223 Remington. I've got several of their pistol cartridge case gauges but these are my first bottleneck cartridge cases.

My understanding was that the case gauges for bottleneck cartridges have two "shoulders" -- delineating the inner/outer limits for proper headspacing. Looking at these dies, there is an almost imperceptible "strip" machined out from the top (and bottom) of the die, of very shallow depth.

So for proper headspacing, is the cartridge supposed to drop in flush with the top of the gauge? Thanks,

Justin
