I realize that a number of our members don't like the NMLRA so they refuse to join it.
Hopefully they won't mind me talking about the November 2008 issues Bevel Brothers column that they missed by not getting the magazine, but I thought it was quite interesting.
Seems we all have heard about ramrods wearing out the muzzles of our guns if they were made out of things like fiber-glass.
Well, they had a question about using fiber-glass ramrods and because they "knew" that only a stainless steel ramrod doesn't contain abrasives or get coated with them that it was the only safe thing to use.
They got to thinking about it and built a machine that would push a short piece of ramrod back and forth in a length of barrel. The machine moved the "ramrods" 7 inches in each direction.
The machine did not have any special provisions for aligning the "ramrods" with the bores so they flopped back and forth as they moved into or out of the barrels.
They then made up some short "ramrods" out of 3/8 diameter wood, fiber-glass rod, solid brass and stainless steel.
They used sections of new .45 caliber barrels they had on hand to test the various ramrod materials. Each barrel was faced off on a lathe and the bores edges were deburred. They did not crown or cone the barrels muzzles.
When all was ready they coated the various ramrods with black powder fouling and added some fouling half way thru each test.
They ran their machine long enough to produce about 30,000 strokes and were quite surprised to find that the only material that actually wore the muzzle was the stainless rod which looked somewhat polished when the tests were finished. The bore that had been tested with the stainless "ramrod" was badly worn. So much so that in the photo it looked like perhaps 1/16 of an inch or more of the bores material was worn away on each side of the muzzle.
All of the other materials (wood, fiber-glass, brass) showed a lot of wear on the rods but the barrels they were used in were in fine condition.
From this I think we can learn that if you are using a stainless ramrod the use of a centering cone is a must.
If you are using wood, brass or fiber-glass barrel wear apparently isn't a big issue.
