Two of the four attendees were shooting new S&W M&P AR15's. One was shooting Barnaul and one was shooting Wolf. I asked and both of them said that's what they shoot in their rifles (because it's cheap) and they weren't having any issues with it.
Previously I've heard the Barnaul stuff was very bad. It might be in some rifles. The point is, try different ammo in your rifle and see how it works/shoots. What doesn't work in mine might work just fine in yours. Every rifle is somewhat different.
About the only "gospel" on ammo is - you can't have too much of what works in your rifle.
Not so much the lacquer "running' as building up so much that rounds won't chamber.
Some rifles do not care for the steel cases. Rough on extractors. Other rifles could care less.
If your rifle likes it go for it, if it don't try something else.

Arc, you're learning!! ;D Good job in your phrasing there!! ;)
The lacquer is more likely to go in to a jell like state, & "accumulate", (some might call it "liquid", usually it's not, unless they are doing some 1K round 20 minute cookoff in full auto....), which will cause the rounds to not chamber correctly..... :-\
And yep...those extractors may not be made for the particular type of "brass" that's running thru the rifle..... :(
And yet again, if your gun likes it, & doesn't break on it, & it's cheap(er), then use that....you'll be able to practice more...... ;D
Kind of reminds me of the old racer saying....."If you have a theory, and try it, and your car slows down, try a different theory"........ :D :D ;D
Why trying different ammo is a good thing....altho some of my better deals have been from folks who bought a whole S***Load of a particular brand, then found out their gun hated it......if it worked in mine, I'd get it at $.20 on the dollar..... ;D
Have a good one all.......Sam, nice job on the radio today....I downloaded the Mp3 version, & will run it thru my "music" software to clean it up a bit, (get rid of the ads & such), then see if it can be posted on our site......very nicely done, Sir!! 8) 8) 8)

This is why Appleseed is so nice! You don't even have to shoot very many rounds to get the job done. You'll almost never again in your life run into a barrel so hot it's melting lacquer because you don't have to. One shot sighter.... fire for effect!
Just for the record, I've been rocking the Silver Bear 62s in my Colt and it's runnin like a Deere.
My Armalite goes bang w/ whatever I put in it. I've run various of the Russian offerings through it. No problems. Not as accurate compared to other loadings. But it goes bang,,,too, I do not shoot long strings w/it,, , even so, I find 'red particles ' on the bolt face & chamber area that does require specific attention. Like I say, I don't shoot so fast & furious as to have expierienced 'melting of the read lacquer' problems. For that , I've read acetone may be the solvent.
The 'gray' coating referred to by 'DuaneRN' is advertised as 'polymer', I don't have too much expierience w/it, and do not know it's 'melting point', I would consider it to be far more lubricious. The zinc coated stuff might be the way to go.
I don't have an AR, but I used that polymer coated wolf(military classic) in my SKS through-out the entire Winona Appleseed with no problems. I have never noticed any of the polymer 'melting' off, or building up.
(On a side note: when it rained at the end of the day, I had about 30rnds loose in my range bag that got wet. I didn't think to wipe them down at the time. and while the few lacquer ones did corrode, none of the polymer did. :o)
The red stuff from arround the primer is my only beef.
As far as the older laquer- coated stuff. It did have more of a tendency to build up. >:( And though it was a long time before it affected the opperation of my SKS, I could see that happening with the tighter AR's. It did, however, clean up easily.
Being that it's relatively cheap, it wouldn't be a bad idea to try in any rifle/caliber. It's not likely to cause any permanent damage. (With the exception of maybe the extractor; as stated before.) Which I believe is a relatively cheap fix. :-\
At Knob Creek we had 1 student use polymer coated wolf in an AR and he 3 cases get stuck in the chamber requiring a cleaning rod down the barrel to knock them loose (not to steal the thread ) . I scrubbed the chamber with a bore brush and solvent allowing the student to finish the second day.
Totz,KY shoot, another AR more wolf (can't remember lacquer or polymer) same results 2nd day, same solution.
Another class, 2 Carbon 15 (match chambers) both using lacquer ,several cases stuck in chambers with case rims ripped off by extractor ,rods needed to knock out cases -1 sent back to factory with case stuck in chamber for removal. Factory reamed chamber to more open specs advised not to use wolf without more frequent chamber cleaning (my personal weapon).
Use whatever works ,know what needs to be done to keep your rifle running with less than optimal ammo ,keep practicing and spreading the info around.
