Every thing cayugad said about the difference between #11's and #11 mags - DITTO
But I have found the most common problem with hangfires for those people that damp patch after shots is the patch is too damp and leaves moisture in or near the nipple.
Another thing I have done is switched to T7-3f in all of my sidehammers - the 3f is small enough that I can tap it out under the nipple and even on the most cold mornings get a get ignition, but I also use Dynamint Noble 1075+ #11 caps. IMO - they are the best.
CVA makes a great pipe cleaner for cleaning the flash channel on a ML also they have bristle material on them that reall cleans the channel...
Good luck...
