do these rifles have that much crud in the barrel? bought it for my son early this summer and really just cant seem to get it clean. i have used window cleaner, hoppe's #9, and wd-40 with really no good results. wet patch first, brush next, a couple dry patches next, then the jag a few times till the patch is clean. go to run rem oil on the home stretch and that patch comes out looking almost as bad as the first.
