A ramrod without any attachments should not extend beyond the muzzle. Other than getting a tip dirty, there should not be a problem. Actually the tip should sit back about 1/4" from the end of the muzzle
There is no safety or practical reason for making that statement at all.
No matter if it sticks out a little bit. Usually the person who made the rod just gave themselves a little bit more rod to grab for use.
For the past 45 years I have made all of my rods a bit longer than the muzzle.
Yours are just fine. BTW, the don't get dirty from the shooting, just use.
