Hard to tell looking at the bore if residue is burned or unburned powder . Make a patch out of a blue shop towel. 1/4 about right for a 12 G. Light lube with oil and push it through the bores.
Take the patch outside and light it with a match. Unburned powder grains will fizz. Dirty bore won’t William |

Also agree with William as test but my guess its burnt powder residue. Some powders have the different burn rates. Learned this the hard way shooting right handed semi-autos as lefty and having some slow burning powder slung in front of your eyes. Also saw some poor college kid at a KA Old South party use modern slow burn powder instead of black powder in a canon, and even standing half way beside canon but downwind got burned very badly. God sometimes does not take care of drunken children. Last edited by Todd Poer; 03-23-2018 at 06:12 AM.. |

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.

Low P loads with 700x? I inherited a large tin of it and have never used it because I've not seen low P loads for it. I recently loaded up 1000 9mm with it just to use it up. I hope it doesn't gum up my HPower too badly.

The 209p might be the issue. I always have 10,000+ WW209's in stock and don't use loads that don't use that primer. Could be I've just not found a low P load using a 209 primer. For the size of the tin I have it would be worth buying some p's to use it up. I think I have the same issue with large jugs of WST and 800-X.

If you're loading at 8000psi or less any of the mild primers will work without a lot to worry about. I'm looking at 16grs of 700X in a Rem hull and 3/4oz of shot and with a Rem, Win, or Cheddite primer and they all have 9300 to 9900psi. If you go down to the 14gr loads they show pressure in the 7000psi+ range.
