Just to make sure I've got the facts right, imanaknut and 1-Patriot you two are talking about the "new" Wolf ammo black box that says WPA on box and no longer the older style with the pic of a wolf on it correct?
I have used and continue to shoot russian steel cased ammo out of my AR; this includes Wolf (the older black box with pic of a wolf on it) in 55gr and 62gr FMJs and HPs, and Brown Bear which of course is lacquer coated and not polymer coated. My AR is a mostly basic DPMS AP4 model with a pencil style 16" barrel; all stock except the magpul stock and foreened. I use the above mentioned ammo during my range's small 3-guns 99% of the time because I don't want to risk losing brass cases in the grass and losing them to other reloaders.
Depending on the course I'm shooting a max of around 40 rounds....unless I'm struggling
. I admit that I'm lazy when it comes to cleaning my AR and have prob thoroughly cleaned it once within at least the last two years. I will oil up the bolt and BCG before shoots, but I'm not wanting to go overboard with cleaning because I'm kinda doing my own "run it until it pukes" test using nearly all steel cased ammo with some brass tossed in. I admit I'm not doing double taps as fast as I can pull the trigger or 30 round mag dumps on a regular basis, but I haven't had any issues with any of the steel cased ammo I've used so far.
A few buddies and I went in on a case of the newly labeled Wolf 'WPA' black box 62gr HPs. I haven't had chance to try them for groups/function yet, but I'm now curious to see the results. Buddy of mine ran some Tula through my AR without issue, but on occasion it won't keep bolt back on his AR after last round in mag.....his AR is 16" bull barrel and I forget parts make at the moment.
I did run my AR a bit faster last year at a two day rifle course using the same kind of ammo above, but still didn't have any issues. The extractor has yet to break and be replaced, but I admit that I haven't done a close inspection on it for wear, before or after.
Chalk everyone's experiences up to YMMV, with each brand of rifle and ammo, or bad ammo batch I guess?
