Reloading necessary to become gm?

Obviously technically you don’t. but how many GM shooters just shoot factory ammo? Specifically for CO, it doesn’t seem to me that reloading offers that much better advantages other than slight savings and softer shooting ammo compared to the amount of labor and time investment. I made B class recently and wondering if it really is that much better/necessary to start reloading my own ammo. Especially since the current scarcity/costs of components don’t really offer much cost savings. Obviously I should just focus on shooting more but just thought to hear from others on their opinions. How many of y’all CO shooters reload?
