I'm so let down The bullets are trash or trash 8 out of 20 we're not even suitable we got 2 out of the 8 to go off very sketchy and I definitely was the one shooting those then that left us 12 that did not have black burn marks why do you say black burn marks because the rest of the what is it copper Copper brass compound whatever the bullets made out of It's turning colors like when I will everyday if I will Or if I touch it with the torch oh like I just did yes it does the same exact thing so somewhere somehow I don't know if you're heating them to cramp on Them to put the cramp
