Do not be tempted to accept reloaded ammo from anyone or buy ammo at a gun show that is not clearly new in a box and correct for that box (head stamps match, etc). Reloading can be done safely, and many do, but you are staking your safety on it. Overcharged ammo can cause catastrophic failure of a gun. Unless you personally know that person and the degree of their knowledge and safe practices, I would not go there.
Your instructor can teach you how to safely use dry fire practice at home with snap caps as a big part of practicing your grip, stance, drawing, sight picture, and trigger control. Dry fire does not use ammo and is a valuable means of practice that instills muscle memory and avoids developing a flinch reaction to recoil. Practice smart. A hundred rounds of just punching paper is not as productive as 50 rounds with attention to each detail you are practicing and preceding it with regular dry fire practice you can do at home.
Glad to hear you are getting some professional guidance. Welcome to the world of those who have learned we are all on our own until help arrives. Now if we can just get a few million anti's to get it.
