wanting to reload .300 fireball

[m1oh7]

Hi im new to this round and reloading in general, ive got a reloading rig already picked out and ive got a few friends that can show me the way with how to reload the rounds once i get the brass


my question is, how do i make .300 brass from .223, im a reservist so i have free access to brass all the time when were over quota for what gets to go back to the ammo point, I read that this is the best way to go if i can do it this way,

im just not sure how the brass can go from .223 to .300, what im looking for is the tools that i need to buy to do it, the cheaper the better but i understand that nothins cheap anymore so im prepared to take a big dent in the wallet

thanks
