Remington and Hornady ammo are available.  Hornady started producing it last winter... and Remington has actually stepped up production for the first time in years.  Check Cabelas if you can - Remington ammo is usually available there.  Also, Grag and Sons has both Remington and Hornady ammo in stock.  As far as we know, all factory Krag ammo is manufactured to be within acceptable pressures.
