You are right, sort of.
I started casting bullets and making patches for my .54 Rocky mountain hawken rifle and my German jäger rifle some time ago.
For cartridge I prefer H&N bullets. They are galvanized with copper and have a resin coating. The bullets allow hotter loads and do not leave any lead fouling in the barrel. For now I decided to buy the bullets for the .45 colt and spend the saved time shooting.
BTW: Reloading is more expensive than factory ammo. Longer and more frequent shooting sessions do more than compensate for lower price per round . As long as reloading and shooting are affordable fun, I do not care. Other people spend money on their hobbies too.
