Just curious how many other experience this..... When I clean my ML, I run solvent/lubricant patch down the barrel, then a brush down it a few times. Then run patches through it until they come out clean. I then run a patch with bore butter down it. Without fail, after cleaning it good, the first shot is always, and I mean ALWAYS, 4-6 inches low. Then the next shot is right where I want it, 1.5-2" high. My ML needs a fouling shot after cleaning. Is this common?
