PMC Eldorado factory 270 Weatherby mag. 130 gr X Copper fouled my barrel by 12 shots so bad the target looked like a 15 yard buckshot pattern. Next 85 gr blue coated xlc in 240 Weatherby mag same chit at that pt I would have done best to beat that Brooks turd into the ground. Fug 'em. One of these days I reckon I'll get stupid and try the ttsx. Mb
I can’t suggest that it’s as important as it appeared to be at one time…..but, try cleaning the bore to “squeaky clean” with a good cooper solvent prior to trying the Barnes. Or for that matter……any mono!
I really think that you’ll be pleased with the new ones! memtb
