IF continually fired at absolute max loadings, the case section just above the belt
will gradually expand to an
interference [non]fit with the chamber. And because it's belted the "normal" resizing die cannot fully resize through
this section as would ordinarily be the case... so it will grow over time. [Therefore the seller's not pulling your leg.]
However
once-fired brass should not
ordinarily give you a problem unless the chamber was overly large to begin with.
Second, loading below absolute max will alleviate the belt/case sizing problem.
Third, partial sizing to
shoulder fit -- as with normal non-belted cases -- will solve the case stretch problem.
ps: get a Stoney Point/Hornady case headspace gauge set.

I just leave on the [RCBS/Imperial] case lube/don't wipe it off.
