I would trust the Hornady ammo to be every bit as good as Remington or Winchester.  Hornady (wisely) stepped up to the plate in a market that was (for some time) sorely lacking... and knocked it out of the park!  Their decision to start producing Krag ammo has had the added effect of forcing Remington to start producing loaded ammo again, as well as several cartridge manufacturers to produce brass.  As long as we continue to buy, we'll keep the demand up, and hopefully keep them all producing for many years to come.
