A question for the gun plumbers on here.I understand how you cut and measure a standerd non belted case when chambering a barrel.How do you measure or do a belted case chamber? Since it chambers on the belt and those belts are not known to be that precise how do you measure or settle on a chamber spec?

Re: Headspacing belted magnums?
You don't headspace off the belt when you reload. You use the shoulder just like
any other round.

Re: Headspacing belted magnums?
Not interested in reloading Im talking about when the chamber is being cut.

There is still a SAMMI spec for this belted area.
Unless someone is going to give you the brand of brass they are going to use all the time, and this is even iffy because like you said all brass is different, one would use the headspace gages.
It is possible to chamber a belted cartridge or any other cartridge, and it could have dead nuts headspace according to the gages. Drop in a piece of virgin brass and you could have bolt movement. Drop in another piece of virgin brass from another manufacture you will have no bolt movement, but it would all fall within the specs.
Most reamer makers are going to use SAMMI specs for the belted portion of the reamer and headspace gages regardless of what mods they do to the rest of the reamer. You can always spec order the reamer to start cutting the belted protion sooner or later but you would need to be pretty dang sure of this if you want all belted brass for your caliber to fit.
Once it's fired formed then the belt is not really an issue again when the cases are prepped for reloading, you worry about the shoulder then.
