Years ago, I used Gold Medallion bore cleaner on my benchrest rifles. When I ran out of it was about the time I quit serious competition, so it wasn't of much concern at that time. Since then I have heard that Remington bought them out, so I bought some Remington Bore Cleaner, as they call it. It is not the same product. The cleaner I'm talking about was brown in color and had an agitator ball bearing in it. It had to be shaken vigorously for each use. The Remington product is white watery stuff with no agitator. Anyone have so knowledge to share on this?
