Goodgrouper.....Hunter\'s Extreme Copper Melt Well like I said I ordered the stuff when I did I ordered the 25 & the 27 cal nylon brushes for my .308 and my .338 Lapua.. I kind of expected the wrong brushes to come because the guy was not really sure what I was talking about undersized brushes and all when I placed the order ...anyways the stuff came today.. with the correct brushes....so I rushed out and started on my GA Precision Rock after about 5 min of scrubing with numerous patches wet with copper melt (No Copper) at all! so I dryed the bore put it back in the safe and moved on to the lapua again NO Copper at all! I have no doubt this stuff really works... I guess I came to the conclusion that I am TOTALY ANAL!! about cleaning my guns...I can get my bores Totaly clean of copper in about 5-10 min using shooters choice and Sweets wiping out the bore in between the two with denatured alcohole..then just drying with a few clean patches...so far the only advantage to this coppermelt is less crap to transport to the range...also it may get my barrel clean in half the time mentioned above with conventional cleaners I dunno yet?..need to go foul my barrel and put this coppermelt to the test! as soon as it quits raining /ubbthreads/images/graemlins/grin.gif.
