I've recently started reloading 300bo subsonic. I'm using 10.5gr CFE black powder, 220gr lead Hoosier bullets and 6.5 small rifle primers. It seems that every once in awhile a round won't fire. I've only made a few at a time then test it out. I just had one not fire and manually ejected it, it didn't even look like the primer was hit. I put it back in and then it fired. I was just seeing if anyone had similar issues or advice on how to fix this. Thanks for any help.
