There is no reason why you can't reload "cheap" boxer primed brass. It not going to affect accuracy. just make sure they hold the bullet securely.
Pistol cases can be reloaded until they split or the primer pockets won't hold the primers securely.
Rifle cases can be reloaded an unknown number of times depending on many things such as how powerful the charge, how much they stretch and are trimmed. I used to shoot IHMSA with an XP100 in 708 Remington and neck sized only the cases and got more than 100 reloads out of them. I still reload them for plinking with light loads.
I prefer to reload nickel plated cases, it's easier.
Steel cases can be reloaded, I have a bunch of WW2 steel 45acp cases I have reloaded a few times. It is very hard on the dies and can only be reloaded about 4 times. It is not worth the trouble to do.
