Ok just starting to reload. Bought a rock chucker SS. I may have ordered the wrong bullets. I thought I ordered 40 cal. Anyway they sent me 10mm .400 diam 155 gr bullets. I have not bought brass yet. I will be shooting a Glock 23 40 cal. My question is can I load these 10mm bullets in 40 cal cases and shoot in my glock. Or do I need to send these 10mm back and order something else. Thanks guys Wanna kill these ads? We can help!
