Just thought i would share my experience on here so that some others might benefit, don't really know if this is the right place but here i go.
I recently (2 weeks ago) ordered some Hornady .204 rifle brass to start reloading from Countryman of Derby, i was very disappointed when they arrived to find three with split necks and another with a pin hole on the case that i didn't notice until i had loaded the round.
That very same day the same RFD contacted me re the arrival of my new GRS Berserk rifle stock i had ordered about 3 weeks prior so i decided to travel and collect it, and complain about the brass at the same time.
Countryman was very good and since i had loaded the remaining brass offered me a small discount on a ammo box i was purchasing but said that even if they had complained to their supplier or Hornady they never get an adequate response.
I did a bit of forum trawling and the opinion was much the same even in the USA when trying to complain to Hornady, not to be put off i visited their website and sent them a polite complaint re the quality of this product i had received, a week went by with no response!
Imagine my surprise today went i came home to find a parcel from EDGAR BROTHERS who i presume are Hornadys importers, with double the amount of rifle brass i had originally purchased inside. I still have had no correspondence but on the delivery note enclosed it says "sent foc as requested by Hornady".
Got to admit, its kept me a customer of theirs.
