Borrowed this muzzleloader from my dad so I could start messing with it with the anticipation of possibly trying muzzy elk next year. Now, this gun has less than 10 rounds thru it (he never hunted with it), but the bolt has some serious rust (guessing it never got cleaned either). I am a complete newbie when it comes to muzzleloaders, so I was trying to figure out what parts I should replace. I am going to order a new breech plug and nipple. The website I found lists a "nipple for musket caps" and then just a "nipple". Which one do I want?
Second, what should I do about the bolt? (See pics below). Can I just clean it up or should I look for a replacement?
Lastly, when I look down the barrel I can see stuff on the inside of the barrel. I'm hoping it is just powder residue, but I'm ultimately afraid that it is rust too. What is a good cleaner to use? If it is rust, is the barrel toast or can I get it clean and still have a good shooter?
Thanks in advance.
