While I agree some Hornet case base diameters are below that specified for the 17 Hornet, PRIVI cases match or even slightly exceed that of Hornady factory brass.

This is one reason why I chose PRIVI cases to make my 17 HH cases... the other reason is they have a neck wall thickness on average .001" thicker than Winchester or Remington.

I can see no external dimensional reason why reformed PRIVI cases should not be loaded to 17 HH pressures, and not leave the cases looking 'pot-bellied'. Internal web dimensions and case volume may be a different matter...

I've finally got around to measuring internal case volume of Hornady factory cases vs reformed PRIVI cases vs other makes

Total case water capacity in grains (all fireformed, then FLS and decapped, flash holes plugged, water with Simple Green as wetting agent)

Hornady 13.40gr
RWS 13.47gr
S&B 13.55gr
PRVI 13.85gr
Winchester 14.15gr
ICI 14.48gr
Remington 14.73gr
