I've been reloading for a little while now and have only loaded jacketed or plated bullets. My question is do cast bullets have to be sized in order to load and shoot them? Specifically I have some cast bullets .45acp and .38spl on the way from Georgia Arms and would like to know if these bullets will need further sizing for me to load and shoot them safely and accurately. Thanks in advance for your help. Wanna kill these ads? We can help!
