I really got turned off to the concept as I watched people I liked to work on shooting skills with turn to reloading to save money. Then our shooting sessions changed from being focused on shooting skills to focusing on their load development and assessing why given rounds failed to perform. I will say this for them, reloading gave them a whole new set of excuses for justifying poor shots and gun malfunctions. "I didn't pull that shot, but I may have gotten a bit much powder in that case..."
Maybe you liked developing shooting skills with them more than they liked developing shooting skills with you. Reloading can be about more than saving money.
