Thanks. Most of my accurate loads I have found so far are around the halfway point. Looking at a .223, but I mostly have 5.56 brass. That's why I askedMost , most accurate loads are below the listed book MAX. But to answer your question , yes. Plus if you are reloading for a bolt action , you can increase your loaded rounds OAL to what your rifle's Mag. will allow, or longer if you single load a round.
Yes. Have done it for decades. For my precision reloads I use the same head stamp brass. For plinking it doesn’t matter.Would it be safe to use 5.56 brass for .223, as long as I keep pressure below the .223 max?
