I always use a bore guide for both range rods and short starters.
True what Chap saidthat for a hunting ML this may be over protective, but if you are like me and shoot several pounds of powder a year, a couple of bucks to help protect the bore of your favorite ML is well worth it.
Really nice brass bore guides available from Track of the Wolf:
