Great googamooga, the nonsense one hears! I am not a fan of the original X-bullets (erratic pressures--but the TSX seem to be perfect. Spectacular accuracy, tremendous penetration and good expansion, and good velocity. If they do copper foul, so what? That's why Brownell's sells G-B Non-Imbedding Bore Cleaner. The only problem I've had with the TSXs is that they squirt out the bore so easily you have to use a lot more powder than standard to get them up to speed. Just follow the instuctions in the Barnes loading manual and smile a lot.
