Home Forums Hunting & Shooting Ask The Gunwriters First experience with Ultra Bore Coat . . .

How does UBC do in a frosty or lightly pitted bore? I have an 1873 Winchester and an 1895 Winchester that shoot good but have pitted bores. There is also red rust visible down in the pits even after quite a few rounds down the tube. Would the rust have to be completely removed? Quicker cleanup would be nice on these old rifles because I shoot them a lot.

Yes, remove the rust and anything else. It won't fill the pits, but it will clean better.

What corelokt said,remove all rust then install UBC. It will clean much easier. It will keep the rust from reforming.

Doug, When discussing medium bores like the 35 Whelen do you find that it is necessary to re-apply after curing and cleaning the first time to assure total coverage of the bore? I don't have a bore scope so kind of guessing here. Bear

Bear,
I haven't found it necessary however,you won't hurt anything if you do reapply. After curing you'll right back to .25 microns. I find reapplication helps only with M.L.due to low heat and pressure.

Even with 65 shots down the barrel to cure the UBC, cleaning was not that difficult. Just let Hoppes #9 do it's work. Wiped out the crud with 3 wet patches and then used a nylon brush to loosen up any touch carbon. Soaked in #9 for about 6 hours before wiping it out and hitting it 3 times with Barnes CR10 to remove all the copper. Looks good! Off to the range in about an hour.

Thanks Doug. Bear

Thanks Doug. Do you have any suggestions on how best to remove the rust? I suppose electrolysis would work but I don't have one of those units. I also have a rust remover named Evaporust that is supposed to remove rust without harming the steel.

Try your rust remover I've always used JB and elbow grease.
