[QUOTE="BrentM, post: 1895735, member: 61747"] I couple years ago I was involved in a test to see why a fouled barrel after sitting a little bit has a POI shift. Most believe a fouled barrel is more repeatable. I noticed that carbon over time goes through an oxidization process and the black or dark gray carbon begins to become chalky and gritty. It also tend to lift off the surface a little. A shot or a dry patch takes that layer off....next shot is back in the group. We also noted a FPS differential from this carbon. So we experimented with a bore snake and dry patch. After the sat for a week or 2 a patch or pass with a dry snake was ran through. The rifle then fired....it put rounds back on track. For me, if hunted 3 weeks ago and fired a couple of rounds, I would not want to clean. However, I will run a patch or snake before heading out. If the atmosphere is very humid (rain, snow, etc) I see the oxidized carbon being even more of a problem. [/QUOTE]
