Surprised you didn't move the barrel back and rechamber.
Not that gas operated barrels can be rescued that way.

Problem is, the barrel they used was from the original kit, and completely shot out. It's probably the least-accurate rifle I've ever purchased.
I don't know how many thousands of rounds it had shot out of it, or what the ammo the Germans used before cutting it up to ship over here, but it was done for before it ever got put in a new receiver. Problem is, on a G3, replacing the barrel is no small task.
Same story with a Yugo SKS I bought. BEAUTIFUL rifle. But the bore was done for before it ever hit our shores. Not pitted, not corroded.. just.. shot out. Those aren't exactly easy to swap out, either.
Both rifles hold minute-of-barn-door accuracy.
Before blasting away with cheap bimetal ammo.. it's worthwhile to consider how difficult it is to swap out a barrel. The barrels in that test shooting bimetal were (according to the testers) "completely shot out by 6,000 rounds." Granted, that was one mag dump after another, but that's also a heck of a lot lower life-span.
Considering that once the barrel is done-for on a great many rifles, the rifle itself is pretty much done for, that's a pretty serious concern. Sure, swapping out a barrel on an AR-15 is quick and easy. But not all rifles are AR-15's."

I'm not sure what you expect the condition of the bores on a couple of surplus rifles to prove other than the obvious fact that shooting a rifle tends to wear out its barrel.
I'll say it again, if coated steel jackets in and of themselves were that damaging, the US military would specify gilding metal jackets for M-80 ball. They don't. The only way to tell what kind of jackets a particular box or belt of M-80 ball has is to use a magnet.
The only way that I could really be convinced that the jackets are what's causing the problem is if the bullets were loaded in identical cases, with identical powder and primers. When you contract with Russian or Ukrainian factories and have them competing with one another to make the lowest cost ammunition, it's conceivable that a lot of corners might be cut. More erosive primers, hotter burning powders, even little things like LOOSE SCRAPED OFF PIECES OF BULLET JACKET around the bullet/case juncture (I think I read about that somewhere...) could have a detrimental effect on barrel life completely aside from bullet jacket material.
I've dug many steel jacketed M-80 ball slugs out of various berms and even after penetrating a foot or more into the ground the jackets still look pretty much like gilding metal jackets. If the plating is what's actually contacting the bore and the steel beneath it has been annealed to an appropriate level of hardness, why would copper washed jackets wear out the bore any faster than gilding metal?
H&K 91's and SKS's (at least those with threaded barrels like your Yugo) are not that difficult to rebarrel, a good Gunsmith can do the job quite easily. In fact AIM Surplus has new, in the white 59/66 barrels for only $55.
To me it's a tool, not a museum piece.
