Truth. I would not like to have found out the hard way, but then, I don't shoot modern stuff like this and have no need for it.
However, it DOES seem in all cases - with you in RoI and here in backwater England - to be ammunition from the same maker that is at fault here. It's especially galling in view of the fact that Hornady are the 'inventors' of the .17 HMR [Hornady Magnum Rimfire] in the fust place.
Needless to say, the cartrdges I mentioned WILL be going back whence they came in the morning.
