That's why I posted. I'm not smart enough to think of things like that. ThanksIf these are chambered barrels, just drill a hole through the primer pocket of a piece of brass large enough to pass the cleaning rod through. Custom fit chamber guide.
It's definitely not going to hurt anything.... Lock that sucker in a padded vise and go to work on it.... Run some oil or grease through the barrels before storing....I hear you. I don't know what I don't know. Seems like a bore guide of some sort would be a reasonable precaution--at least to me.
Pure “BLASPHEMY” ....... LoLThere's soooooo much stuff on cleaning barrels out there it will drive you absolutely nuts.... Let me just say my opinion.... I have rifles that were my grandfather's who shot them and hunted with them his whole life.... They were definitely not ever cleaned with a bore guide since I doubt they existed.... They were cleaned with whatever rod came in whatever cleaning kit that was available and I can assure you none were coated since once again there was no such thing.... Every one of those guns , pistols , rifles and even shotguns still shoot as good as they did when new.... Alot of the time these hunting rifles were just dosed in wd-40 and wiped down after coming out of the field and shoved back in a gun cabinet.... Sounds crazy but that's how most guns were cared for back then.... If they were cared for that well at all.....
I don't shoot them a ton of course but the other day I replaced a scope becouse I bought a new one and move everything thing down the list swapping down scopes from one rifle to another , when I get to the bottom gun that scope that was on that one goes on a shelf.... That rifle , a 600 Mohawk in 6mm rem put the last three Bullets clovered all touching at 100 , the bullets were simply blue box federal not even handloads.... I understand why all this new stuff exist but if pushing a decent rod down a barrel at the speed of smell is the problem I think there may be different problems.... I do now clean with coated rods and bore guides etc but it is strange that 50+ year old rifles that have never seen any of it still shoot great.... Maybe the old rifles just don't know any better.... This is just my life experience and opinion so take it for what you want.... It doesn't cost anything...
Edit... I also have a good sized box of the latest and greatest reloading and cleaning crap that I give away to people who want to try it all the time.... I just stick with what works for me now because I am tired of chasing good money after bad and I bet I am not the only one....
