Last year I helped a friend who is a hunting season ml'er only get his two guns in order. I gave him instructions, supplies and even a couple tools for maintaining the rifles. One of them was (yep, past tense 'was') an inline. Well, he loaded that monstrosity, ignored almost everything I told him to do and popped the cap with no ignition to watch Brother Buck just walk away. He took it to a machinist who used an impact wrench to remove the breech. In the process the threads and part of the barrel broke off. That mess is now in the trash. He has a good experienced ml'er friend (me) who could have helped him but, instead, he went the impact wrench route.
And,- AND - he has a CVA Mountain Rifle also. Used that for his hunt and, again, let Bro Buck walk off. He used #10 caps on a #11 nipple. Oh, well. I did what I could for him.
