OK as promised here's the results of some measurement data I collected on Highland (PRIVI), Winchester and Remington 22 Hornet cases.

Neck wall thickness measured on a Mitutoyo digital ball micrometer, rims on a Mitutoyo digital vernier.

It can be seen that Highland has the thickest neck walls on average, followed by Winchester and Remington with the thinnest.

Despite having to produce ammunition to CIP instead of SAAMI specifications, Highland brass did not have the thickest rims as I had anticipated.

Thickest rim was Winchester, then Remington and Highland with the thinnest by a small margin.

Case diameter just in front of the rim was 0.2945" for unfired Hornady factory ammo, 0.2945" for unfired FLS reformed PRIVI brass, 0.2930" for once-fired FLS Remington Hornet brass and smallest diameter was 0.2925" for once-fired FLS Winchester Hornet brass.

So it would seem PRIVI brass will not be likely to have that slight 'pot-bellied' look when fired vs the smaller diameter Remington and Winchester brass.

Anyway, hope this is of interest to those forming 17 HH brass from 22 Hornet...
