I posted my question (above) on some other forums and one fellow wrote in and said Missouri Bullets is selling the bullets pictured below for the 300 Blackout. Has anyone tried these out yet? They are a whopping 245 grain which is well above the charts for the Hodgdon powder I've used so far. Anyone have a guess as to how much H110 to use with a 245 grain bullet?
These look huge and might double as fishing weights!
