If you really get into going through a lot of cast bullets, you might think about getting a pot and molds for whatever calibers, and casting your own. Wheelweights will give you a semi hardcast slug.
Of course the usual disclaimer of melting and casting to be done in a well ventilated area.
Used to reload.357 and.44 years ago. May have to start again....bill going through our state legislature to impose background check for ammunition, along with a 20 round limit in a 30 day period. Makes it tough when you go through 100 rounds a month in .38/.357, .45, 9mm, and .380.
