[lang=sv]This works fine for me since 32 years back and I shoot cast bullets to 90%, about 5000 per year, jacketed fouling is even less hard too get rid off.
No noticed damages to guns from my method, one of them now got over 100.000 rounds through it and was always cleaned by this method
1. Wipe all exterior surfaces clean of the lose lead, powder and lube residue with a thin cotton cloth (old sheets are the best) lightly saturated with any gun oil or mild solvent.
2. Push a clean cotton patch of the above cloth through bore and chambers, brass jag and snug fit with good resistance. Next a patch soaked in Hoppes # 9 a couple of times let sit for minimum 20 minutes but the longer the better
3. With a real tiny paintbrush saturate cylinder exterior, inside of top strap, recoil shield, crane are, forcing cone and rear of barrrel/frame with Hoppes # 9 let sit for min 20 minutes.
4. Scrub all surfaces step 3 with a hard toothbrush where brush is cut down real short so it gets stiffer, then wipe clean, repeat saturation & scrubbing/wiping until clean. NB little scrubbing and wiping is needed Hoppes # 9 solves lifts the leading off in increments until eventually totally gone For the topstrap/barel attachment area a copper or brass brush may be used with moderation for stubborn leading. The hardest area to get clean-clean, is the cylinder face but here I use the cut down toothbrush and rug only, repeat steps 3-4 until clean.
5. Push snug fitting clean patch through bore and chambers, folllowed by a couple of strokes with snug fitting Hoppes # 9 soaked patch.
6. If still traces of leading in bore/chambers I apply a few strokes with a spun or regular SS-bore brush this will not wear/hurt the bore/chambers
7. If still lead traces around barrel attachment to frame and topstrap then I carefully scrape this off with a scrape & pick that I made of soft copper plate/wire, this will not harm the finish.
8. Finally wipe all exterior and cambers/bore with a clean cloth with any thin gun oil.
The above may appear a struggle but the more frequent you clean the less work. I typically do this after every second to third shooting session and then I do like five guns at the time. By this I can minimize the waiting for the Hoppes # 9 to work and it will all be done in less than an hour
I avoid any steel wool or steel brushes on exterior surfaces since this may wear the blueing or polish up the SS-guns and even round sharp edges in the long run. Tried a bunch of solvents but for me Hoppes# 9 is the winner. I avoid plastic jags since the thread breaks off when pulling, at snug fit patch they are good for pushing only. It is my opinion that snug fitting brushes and jags is the trick of the trade when it comes to lead removal of bores, one can really feel and hear when it catches the leading and then drags it lose.
I rarely take off the grip panels when cleaning unless it was raining hard but I do indeed make sure that the grip frame part is coated with a thin coat of oil or grease.
For stubborn cylinder face leading/carbon e.g. severely neglected cleaning it is sometimes worth to dismantle the cylinder from the frame, this make the rubbing and scrubbing easier.
Never ever scrape lead off with any steel tools like knifes or screwdrivers VERBOTEN!
Never clean heavy leading out of bore by firing jacketed ammo, this can severly damage bore/barrel thread may even brake off thread. The lead becomes like a wedge between the bore and the jacketed bullet and nowhere to go so pressure increases. This was a common practice over here among magnum shooters and resulted in destroyed guns, even one "indestructible" GP 100 was destroyed by this practice
The Lead removers are excellent tools but with my method I do not any longer feel that I need them.
Avoid lead removal cloths on blue guns exterior. Avoid the cleaning pastes since they can be slightly abrasive, they are hard on blueing and they polish glass bead or brush finish SS-guns shiny. However for the bores they are fine..
Hope the above can be ofsome guidance and it is not as much work as it may appear, with some practice it will not take too long.
