The Hornady load is produced by CCI for them. They make the bullets and send them to CCI for loading. Hornady will put any color tips in those bullets that CCI specs out for various other companies, too.
They made the 33 gr. bullets for the Remington load, too, a friend of mine has got a bunch of them from contract overruns, they shoot pretty good with the right loads in a .221 Fireball, too. I don't know that CCI makes the ammo for Remington, but it's a good bet. Winchester is the only outfit other than CCI who makes .22 Magnum, stateside.
