I am puting the finishing touches on my semi custom 223 AI that I have been putting together over the past year now. Its time for me to start thinking about the reloading portion of this thing now so I am looking for some advice on which powder to try first. I completely understand that every gun is different and not all powders are the same but, I am looking for a good educated place to start with. I have a 223 AI chambered 22 inch CBI 1:8 twist barrel. I am planning on trying to run the barnes 62 gr ttsx bullets out of it. I am wanting to use this rifle for coyotes and doe. With the barnes bullets being solid copper bullets I am looking for as much speed as I can get with good accuracy and stay within safe limits of the rifle. Typically I don't care about speed but, the barnes solids coppers from what I have read do require a little more velocity to open up properly on animals.
