700X isn't the cleanest burning powder but I shot it for years with no problems. It's only as dirty as the last shot. Every gun could pattern the same load differently. The wife's little 28ga Beretta wouldn't pattern 8 1/2's worth a darn, but 8's or 9's were just fine. I don't know what the pressures were, but you could try a 1/2gr more of powder and see how it patterns/burns. Good luck.
