As regular readers of this board will know I've recently rediscovered Ed's Red, see sticky at the top of this forum, and excellent so it is it has no copper removing properties and doesn't claim to either.
I've been aware for years that ammonia does the business with the copper but getting some at the right strength had been an issue, not that I'd pursued it that hard but in the supermarkets you just don't get anything like a 10% ammonia solution. Probably banned by the EEC as too dangerous for wimpy people that can't be trusted to be responsible for their own actions.
Well yesterday whilst lurking about Homebase whilst waiting to have new tyres fitted to the Land Rover I came across some Homebase own brand ammonia at 9.5%, well I bought a couple of pints didn't I.
I've now tried it out neat on the No5 I used down at the CQB shoot last weekend, 300 rnds of HXP fouling to shift.
Boy does this stuff work on the copper and everything else.
I've spoken to a chemist friend of mine about possible side effects and evidently this stuff is hygroscopic so don't leave in the bore for long or you'll get the full corrosive primers effect and then some.
My drill at present is wet the bore with neat ammonia using a nylon brush, leave for 5-10 minutes but not too long as it has low viscosity so runs out easily, then dry patch.
Repeat as neccesary and then finish off with a good scrubbing of Ed's Red to give a final finish and remove the hygroscopic ammonia, dry patch and a final light coat of Break Free.
Does the job and cheap to boot, Hoppes No9 Benchrest is around £10 for 4 fl ozs here.
