Or ammonia ?Doesn't Ez-Off have some type of an acid in it. I know when my wife cleans the oven there is an acid type of smell. Could be hard on the bore, maybe.
I've been testing Free All penetrating oil, available in our automotive supply shops. It seems ro soften the carbon to the point that it is more easily removed.I scrubbed this barrel with JB Bore paste for 2 hours, 20 strokes with each new patch, it hardly touched the black stuff…
This was a new REM 700 LR in 300WM, then I got the new REM 700 Sendero II in 7RM, and it had the same black deposits, which you can 'feel' with a dry patch
I cannot get Iosso here, does anyone have borescope pics of before and after?
Cheers.
Thanks for the heads up, but our chemicals here are very limited.I've been testing Free All penetrating oil, available in our automotive supply shops. It seems ro soften the carbon to the point that it is more easily removed.
Perhaps this or another carbon remover is available to you. I've also found that Iosso or JB Bore paste used in conjunction with it helps. Just another tool in the tool chest.
Removing stubborn carbon deposits is a chore no matter what. We're just finding more efficient ways to remove it.
I'm liking that free all more and more.I've been testing Free All penetrating oil, available in our automotive supply shops. It seems ro soften the carbon to the point that it is more easily removed.

I tested the free all also. It didnt remove the hard packed carbon but did remove the powder fouling and loose carbon. It has a nitrocellulose solvent in it but after the nitrocellulose is burned it is just carbon and it is hard packed by the bullets. JMEI'm liking that free all more and more.
Do they not test fire the rifles before leaving the factory? Sure looks like carbon. Either way, it certainly is stuck on there.Thanks for the heads up, but our chemicals here are very limited.
Those barrel pics I showed are not from firing, that is what was left in 2 barrels that I cleaned straight after purchasing. I believe it is from whatever lube Remington used when those barrels were buttoned.
The SPS was 2015 build and I bought it in 2020, had been shelved all that time.
Cheers.
