Hornady .17 & .22 Hornet loaded ammo

[9.3 Mauser]

Who has had the latest dished head ammo problem from Hornady in either .17 Hornet or .22 Hornet besides me??

Hi,
Yes I have noticed, (with the naked eye), and had the 'dished head' problem with Hornady 35gr V-Max .22Hornet loaded ammo, in the last box of 25 purchased, with my Anschutz 1730 rifle,
but manifesting itself a bit differently.


The Anschutz has a very tight headspace/chamber tolerance with it's flat chamber face, and they are much too stiff to close the bolt on for my liking,
so I just fired them in my Savage, which has more tolerance, probably due to it's cone chamber face, and chambers them a bit better,


and then biffed them in the bin.


I didn't look at the spent primers, though, sorry, so I can't comment on that.


Just loading my own in RWS and RP brass at the moment which chambers and bolt closes just right.


cheers,
SS

I haven't fired any facory but have been using the Hornady .17 Hornet cases loaded to 3500 for the 25 gr. and 3750 for the 20 gr. and the heads are flat as can be before and after firing.  Are your case heads dished before firing or only after?

My case heads/rims were dished before firing,
and very tight to close the bolt on with the factory loading.
One or two thou makes a lot of difference when you're headspacing on the rim with a tight spec'd bolt/breech face.
cheers,
