I was trying some new handloads out the other day and out of around 25 rounds fired, I had these two duds that happened. Both rounds were rechambered after the initial misfire and I attempted to fire them again with no luck. All of the rounds fired would have been loaded in the same session and used Federal GM210M. I haven't had this issue with any other rounds fired in this rifle so where would I start looking to pin down the "why" of where my issue lies?
