And I have to say that running any kind of steel wool down a decent bore gives me pause. But that's just me.

Howdy: back when I wuz younger, I shot my Remmy 722/.222 over 50 thousand rounds before it started going over 1 moa ... and was always scrubbed clean with 000 or 0000 steel wool on a brush wet with ( back then ) Hoppes 9 and then followed by an oily patch to push the gunk out. That took about 20 years, not shooting rapid fire, and most all ammo was 24 gr BallC( 1 or 2 ); 50 gr Hornady SX, a mild load thru a cool barrel ...
Later, that was also my favorite way of cleaning my 40X BR in .22 LR; 4X steel wool and almost anything, usually RemBore Paste or similar, then a patch of any light oil ( Kroil ).
I also use that method to clean all the rifles and take off barrels that go thru the shop here, but I do ask the owners if that is ok with them. faster, does a better job, never seen any problem ( yep, got a borescope ) ....
Of some interest maybe is that of my .22LR competition ammo had some moly applied, that stopped any barrel leading( and any need to clean the barrel ahead of the chamber ) , but not the lead gasket that built up ahead of the case ( the little space ) .... never did get that figured out, then my smart pills arrived in the mail and I quite shooting .22 LR in competition (g ) .
All the above just to make a data dot on a blank paper, about like a fly speck on a horse's butt; you can interpret ” as necessary ” . (g) ...

Although I haven't used 0000 steel wool in a barrel, I have a Lyman mold that, every time I use it, has irregularities on the nose that won't go away until I wrap the steel wool aroung a wooden dowel and polish the inside of the mold, spinning it with an electric drill at low speed for a minute. I've cleaned that mold with everything I can think of the the problem persists until I polish it before use. The molds are stored after use by cleaning with denatured alcohol and lubed with a medium weight anti-corrosion coating and sealed in ziplock bags with dessicant. (I've lived in FL and TN most of my life and himidity seems to always be in the 90% range).
Anyways, after 22 years of that, the mold still casts bullets .3092 on the fwd band. No measureable change in diameter.

I apologize for getting off-topic.
Heh Heh, in the war against the 3 moa usual cast bullet group, I am not sure there is ANYTHING that is off topic (g) .... I figger if it's fun, its on topic. regards, ken at deltawerkes
