I have this mould and have been considering attempting to use it in the AR. I have the NOE 311414 working pretty darn well and would like to venture into the lighter bullet for supersonic plinking. We can't have cans in IL and my kids like to shoot the AR at steel.
Has anyone here tried this combination? If so, what powder did you settle on? I have almost any powder I would want to try and will likely start with 4227 or an H110 variant that is about 10% faster than consumer H110. I could also go to 296 as well.
