Thread: cleaning bore/copper/blue?

Then a patch with Sweets let it soak a couple of minutes run a clean patch should be spotless if it has blue then scrub with Sweets
on a Nylon brush and patch until there is no blue, finish with a patch of Hoppes or a good gun oil, Don't leave Sweets in a barrel more than 20 minutes it can etch the barrel,"so I have heard", some of the new solvent are said to be better than Hoppes the Bench-rest crowd swear by Butches products if you are in the market would be worth a try.

What i do but a lot less passes, but then i don't shoot for the sake of shooting much, new barrel on the 303 requires about that to come clean but everything else is just a couple of patches.
