no this was Norman Clark several years ago, however isnt it strange that two of the finest riflesmiths and barrel fitters in the UK have the same opinion?
I wish I was surprised that so many people think they know better than people who have a combined experience of over 5 decades dealing with rifle issues and who have forgotten more than most people on here will ever learn about gunsmithing and rifle husbandry.
A boresnake is often used instead of cleaning properly with a one piece rod. Thats the issue.
Will the cloth ruin a crown? No- will the cloth with glass hard miniscule fragments youve just removed from the lands? Quite possibly. Were the 'tests' mentioned previously done with a clean boresnake on a smooth piece of metal such as the outside of a barrel or were they done with a dirty boresnake on the crown ?
If you have one for field use if you plug barrel, fair enough, although for me it would have to be a big plug of mud to get through the over barrel moderator. I do carry a nylon covered pull through and a patch if needed which I keep in the vehicle and will return to uae if I must.
Ah good, that's two well known rifle smiths then. I did think it a bit strange that only one of them had that view. Let us hope some others chip in with more information to support their contention.
As far as thinking one knows better than experts...we can only decide if we agree with what they say based on our own knowledge and experience.
I only have my 50 years experience of hands on working with (forging, machining, manipulatiing, abrading and polishing) metal professionally to gauge what I think is going on with a bore snake as opposed to any other cleaning system. Of course I may be wrong, I certainly do not dispute that. Hopefully I am still learning and open to learn where I have been going wrong.
It is true I have only been cleaning my own guns for just over 40 years and using bore snakes regularly for just 4. Presumably though, given their opinion, the rifle smiths quoted have not used bore snakes much themselves at all, and there must be a large element of conjecture on their part that a boresnake was solely responsible for damaging their customer's barrel sufficiently to require replacement...unless they were present at every cleaning or responsible for causing the damage with the boresnake themselves.
Do you think that any glass hard miniscule fragments removed from the lands by a tightly fitting cloth patch on a hard jag are any less likely to damage the crown or bore than those on the slightly squishier bore snake? Same amount of abrasive particles in the barrel whichever bit of cloth carries them along the bore and out of the muzzle. Arguably the boresnake may retain some of those particles, and if not cleaned (I shake mine out every time, but wash it rarely) could reintroduce them to the bore on subsequent uses.
To what degree your glass hard particles exist and how abrasive the powder and carbon fouling itself may actually be I do not know. I confess I also don't know what the equivalent abrasive grit size of any miniscule hard particle left in the barrel could be. Just before I pull my cloth bore snake through I have pushed a lump of lead and/or copper through at 2900fps and that was a gas tight fit to the internal surfaces of the barrel, so any remaining particles are likely to be much smaller than the finest rouge powder and can only have a very mild polishing effect, if any, on the barrel when lifted and carried by the bore snake or cloth patch.
With my current knowledge and experience I can't see how boresnakes can be any worse than any other cleaning system.
I await with interest an explanation as to how and why they are so much more damaging than using cloth patches on a jag.
