When my accuracy shows any hint of falling off, it's usually a simple indication that the barrel needs cleaning. It can vary by barrel, but some powders and bullets don't play well with others. Thus, you might try a good thorough cleaning, removing all copper and carbon, then try the A-max factory again, with the realization that it might take a few shots to find its groove. Just a thought...
