Shoot junk ammo, get junk results.

"Back in the day", guys used Spic-and-Span in water to clean rifle bores after firing corrosive ammo.
Slamfire above gives a great description of how to clean the bore. I've done this after firing known corrosive ammo.
On non-corrosive ammo, I clean the barrel on the second day. Why? Because residues get blown into micro-cracks in the steel of barrels. So, you get back from the range and clean your rifle. It's all shiny and clean ... except that on day #2, you look and it is dirty again. How can that be?! By day #2, the barrel has totally cooled / shrank back, squeezing the crud out of the micro-cracks. While firing last week the barrel of one of my rifles got so hot it would fry human skin.

Wow. I immed. recognized the words as Polish,
And watch for whichever vintage of Lake City M2 Ball. Know who you can ask about it.
I used incorrect —online— info years ago and partly-trashed the Bore of an excellent condition Garand from the CMP.
A guy retired from the Navy Rifle Team told me that it —was— one of the better M-1s he had handled.

And this is the problem with some foreign made ammo, most ammo made for military contracts will be corrosive primers, I'm told it's a longer shelf life. So any factory may have a few crates of it around, even if they're also making non-corrosive for civilian sale. Maybe it's a mistake, maybe it's just something they sneak in if that's all they have.
I've bought both Wolf 7.62x39 and 5.45x39 and gotten a batch of corrosive rounds that were advertized as non-corrosive. Wolf is just an importer, they don't make their own no who knows what factory it came from.
I shoot a lot of surplus Yugo m67 and 7n6 thru ARs & AKs and just flush em with a bunch of hot soapy water and re-lube with Ballistol. And if I don't know where it came from, I treat it like corrosive.

Pour Hot water, scrub with some dry patches, then dry the bore with even more patches, then aim a hair dryer into the chamber.
