Conventional Parker Hale jags, solvents and 4x2 patches are doing the job well enough by inspection. I'm using a 308 so it is less inclined to carbon foul using BM8208 than say some other slower powders.

I find that it cleans up well without scouring it out with abrasive paste. I see one of our club members using Autosol on a regular basis and can't help but think that he is shortening barrel life substantially using the stuff.....

When you say regular non abrasive cleaning is getting the carbon out by inspection, is this an inspection with a borescope? There are a few shooters in my area who have brought a swag over barrels around to my place for a bore scope inspection and nearly all swore the barrels were clean, but must have throat erosion as the accuracy has gone off. The regular comment is that they clean until patches come out clean, so there must be no fouling left in the bore. The majority of these barrels which have had a reasonable amount of use had carbon build up in the first few inches and a quick abrasive session brought them back to metal, and 12 fouling shots brought the accuracy back. I am now like other bore scope owners and give the barrel an abrasive clean every 200-300ish rounds.

Kenny Adams uses Iosso in the throat every clean. And look where it got him....

I do use on a much regular basis Remington 40x cleaner. Use to be called Remington Bore Cleaner and before that it use to be called Gold Medallion. I feel this does a better job on the carbon fouling/build up vs. regular chemical cleaners but again not as aggressive as the paste cleaners and much safer.

Interesting Frank. I used to use Gold Medallion years ago.
I have not seen it for many years

KG2 is also good for regular use don't let fouling build up in the first place and you won't have to scrub the begeesus out it to get it back to acceptable
I purchased some VFG felt pellets that tread onto a special jag and work very well.

Hi Richard, thanks for that. I haven't seen those VFG bore pellets but they look like a great idea.

Same stuff buddy! Remington bought them out years ago.

Thanks for all the input. I have a second question.

It's often said that the major issue with pastes is when people don't clean it out properly.

How do you clean the pastes out of your barrel and what are you looking for to convince yourself there is no grit left in the bore?

Cheers again.

When the patches come out clean after an abrasive clean you might think its all out- saturate a soft nylon brush with hoppes and scrub back and forth down the barrel pushing out each end. Then follow with a wet patch and see how much black stuff comes out

I patch out with metho saturated patches until they're clean, then dry patches, then give it another dose of Sweets 7.62 treatment. I say another because I usually precede the abrasive with Sweets.

Thanks for the replies Brad and Alan. After the paste, I've been dry patching, then brushing the barrel out with carby cleaner and a nylon brush, then patching the barrel out with carby cleaner soaked patches until they're clean and then dry patching again.

As an experiment I might run some solvent patches through the last one again just to see if there's any residue.

I'd love to hear Frank Greens take on what's required here. Hope he see the question.

I'll basically back up what Alan said. Run some wet solvent patches down the bore and see if they are coming out with any black color on them. If you are you don't have it all out. I would use Hoppe's #9 but don't see why the Sweet's wouldn't work just as well. Again I'm not a fan of the heavy paste cleaners.

One of our well known F-class shooters over here used Iosso in one of his barrels several years ago. We made him 4 at one time. I guarantee he didn't get it all out before shooting it again. He brought it into the shop for us to look at it. The tops of the lands where dull/hazy looking and with some abnormal looking scratches. Not deep gouges but faint looking scratches. The grooves didn't look as bad. I feel he didn't get it all out before shooting the barrel again and between the bullet and the left over paste is what caused it. The barrel would copper foul so badly that the accuracy would go sour in approx. 15 rounds.

We made him 4 barrels at one time out of the same lot of steel and the only one he had a problem with was the first one he used the Iosso in. The barrel he had a problem with had less than a 150 rounds on it. I got him not to use the Iosso in the next barrels and he had no problems in any way shape or form.

Again if you use it pay attention to what you are doing is the best thing I can say.

Thanks Frank, I really appreciate your advice.
