Im not sure what kind of fouling your refering to.. But lead fouling seems to be an industry standard.. I have never bought a target 1911 barrel and am here to work on my 9mm.. back tobarrels.. A 2500.00 black pwder sharps i bought came with breakin insturctions.. if shooting lead, shoot two rounds, clean from the breach and repeat for 20 rounds.. Or to do Do this with jacketed shoot one round and then clean, repeat for ten rounds.. And this is the finest looking new barrel ive ever seen. ... So a rough barrel will need alot more..A black powder .62 call barrel took lots of steel wooling and 1000 rounds before it came around.(be very carefull at the muzzel... I dont like shoot lapping it will make the breach larger than the muzzel.... If it leads, or what ever and is milled properly it could just need to be shot in... Put 500 rounds or so hard ball thru her, and clean meticulously after each 10 rounds... You cant break in a barrel with junk in it.. I think that may be your problem... Or you could call them and tell them its problem... If they are a good company they want you to be happy... Or they may tell you how to break it in... And never use a stainless steel brush... dave
