    Bought a thousand round box of Wolf to try in our DPMS ARs. DPMS recommends no lacquer coating but says nothing about the newer polymer coating process. A good source on the internet says that "all ammo produced by Wolf is now polymer coated which solves the problems of the coating melting and sticking to the chamber/bore". The gunsmith at Gander Mtn does not recommend "cheap foreign-made" ammo, but in the same breath said that polymer coating will work ok for me. He recommends a very good cleaning after using cheap ammo. Anyone use Wolf in their DPMS AR.

    the problem is that steel cazsings dont fire-form to chamber size, therefore hot combustion gasses blow-by into the chamber. this fouling heats the polymer or laquer and leaves deposits in the chamber.

    The only time you should experience a problem is when running brass after Wolf. The brass will fire-form and expand to the chamber dimensions, thereby being jammed into the chamber by the deposits on the chamber walls.



    Doesnt matter if its a DPMS or a Noveske.

    I prefer Wolf 62gr in my RRA. cheap, and performs well for me.

    My DPMS M4 needed to be sent back for a 'warranty repair' despite it was me that decided to run cheap lacquer coated ammo through it. I've had misfires, and damaged casings, but this malfunction was impossible to remove. No matter what I tried, this thing was stuck. I have to admit, DPMS didn't have to do a thing for me and they helped me out for no charge. That's good customer service! I haven't run anything but brass cased ammo since then and there have been zero issues.

    It was probably a manufacturers error from the begining, IE an out of spec. chamber.

    nah its what happens with lacquer/poly cases. had it happen a few years back before i started loading my own 5.56. had a m16a1 barrel on my colt sp1 shooting wolf. then fired some brass case got one stuck so hard it ripped the rim off. i had to use a hammer and cleaning rod to get it out.

    just dont mix brass and lacquer/poly and dont rely on lacquer/poly for ohsht stockpiles.

    this happens with ak47 and sks and mini30/14 too its not just a ar issue. mixing case types is a no-no. you just dont see it much in 7.62x39 since there is almost no brass cased ammo out there for em. my best bud back in tejas his ak would jam up like that running brass pmc 7.62 ammo after the ruskie cheap stuff. had to get a piece of wood and a hammer to pull the bolt back.

    I don't know about others but no issues in my two ARs (chrome lined chambers) mixing up brass and steelcase. Doesn't matter which goes first. And I don't buy it that polymer depsoits are left in the chamber, no evidence of that in mine.

    I shoot tons of Wolf in my ARs. I had a couple of stuck cases after getting them REALLY hot and allowing them to cool down with a round in the chamber.

    Now after I run them hard, I eject the round from the chamber and let the rifle cool with an empty chamber. No more stuck cases.

    Wolf in my AKs has never been a problem. I don't use it in anything else.

    I was shooting brass 100+ rounds swiched to Herters Steel Cased shot 100+ rounds then went back to brass with no issues. That was in my Delton w/ non-chrome .556 chamber. It will put out a good group once in a while w/ steel cased also. Some rifles just dont like it I guess, but mine sure do. As for not forming to the chamber my brass comes out dirty in my .556 chamber ARs but clean as a whistle in my .223 bolt rifle.

    I don't like steel cases and you can't reload it. I think it's harder on the chamber and everything that it contacts from the mag to the ramps. The steel is harder then brass and is certainly harder then aluminum if you have an aluminum framed gun. Brass seals better and IMO results in a better round.

    I'm not trying to start a debate, these are just my views.

    Actually you can reload steelcase if it has the boxer primer. Probably not worth the extra bother when you can find brass instead - but can be done.

    Steel is harder than brass but I don't see the soft steelcase as being much of a problem as far as wear. And even if there was a small difference it would take tens of thousands of rounds to make a real difference. You'd save much more in the cost of the ammo than in repairing the "damage".

    There was a great article copied onto one of the forums that dealt with reloading Wolf steel cases. They had very good luck with it.

    And I agree about the wear. Minimal, at worst.

    I understand people who don't like it or want to use it, though. I will not use it in my M14s.

    I wasn't trying to start a debate. I'm looking to learn something.

    I used to not use steel cased ammo in my ARs. Things have changed after noticing many guys using steel cased ammo almost exclusively in their training rifles. One of the guys I speak of probably puts 1k a month or so through his rifles. Theres guys that do more than that. Replacing an extractor every few thousand rounds or so isn't that expensive.

    Polymer or Lacquer

    So, what was the final verdict regarding the original question about steel-cased lacquer or steel-cased polymer? Anyone know the difference between the two? Thanks!

    Either one is all right in most ARs. But it's harder to find lacquer today. Buy a small amount of polymer and give it a try.
