I think just the opposite. I think todays craftsmanship, materials & rifles in general are twice as good as the old ones (if not even more so) & there will be More rifles around longer & they will be in better cond. (in general) 300 years from now than the ones we are looking at today. .
You must keep in mind we are only seeing maybe 1% of what is left of the old ones. Not every gunmaker was a really good craftsman, they were just able to cobble things together. The good ones were well known & made fancy stuff & they are still here because of that, they were saved because they were really good or really fancy. A handfull did awesome work, fabulous carving, jewelers engraving & etc., some did just crap work & it worked & that was it. For some reason some people like to fantisize all gunmakers of old were really tallented & special & etc........ they were survivors, but lots of times not special in any other way....
You can go to TN today in some of the old gun & antique shops and see some of the most god-aweful poorly ugly built shotguns & rifles you ever saw, look at them & realize they built with what they had & they were NOT good craftsmen, just determined to make it work.
Gun making is no different than lots of other crafts. Some do it fabulous, some just get buy & we wonder how........
As for the Ramrod of the original post..... Sounds like a good idea & see a ad in Muzzleblast of the same thing.
No, have never seen one in hand or used one.
PC ? no......... But if it looked decent I would not hesitate to try one.
Should it be perfect & be PC ? No..... (IMHO)
Never saw an OLD ramrod that was perfect.
