Are most of you rolling your own or buying factory HC?

If y'all are hand making these, is there anything special outside of the typical cast bullet kits they sell to reloaders? If so, what equipment do y'all recommend?

Does HC foul a barrel quicker than jackets to be a major concern?

If you're buying HC bullets what factory brand you using?

Does the diameter increase, between 9mm and 45 for instance, have a greater precedence with HC bullets, or is it a moot point like the more commercial HP rounds?

Trying to learn, thanks for the input!
