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
