(My first post - a question) I recently decided that I needed a .22 magnum and found a Marlin 925m with a Tasco 3x9 40mm scope at the first pawn shop I visited. The bore was dirty, which is what I have come to expect from pawn shop guns, but overall it appeared to be in decent shape and I bought it. My first test resulted in about 40% failures to fire and 30% failure to eject. After replacing a blunted firing pin and bending the ejector wire to the proper position the second test had zero failures. And after cleaning the bore was perfect. My question concerns powder residue in the magazine well. There is quite a lot of powder residue on both sides of the magazine well. Is this normal for these rifles, or is this an indication of a headspace problem? I do not see any other obvious signs of a headspace problem.
