I'd like to see the same tests using AK-47 rifles chambered in 7.62x39 mm with chrome-lined barrels. It would be informative to see any results differences between the AK and AR rifles. I would guess the AKs might fare better because of somewhat looser tolerances in the rifles and a lower velocity caliber, but I could be wrong.
Saw this a while back the test itself was a done pretty well.
All the big money is in Stoner rifles now so I doubt anyone is going to do it Gray.
Besides the AK is pretty much designed to work with steel case so there is no real controversy to address as to the dependability of the rifle and ammo as exists on Stoners.
It's not so much the cartridge case as it is the short term wear on barrels from 'bi-metal' projectiles with copper wash/copper plate on soft steel jacket. They'll eat barrels, particularly those not hard chrome plated or Melonite treated. So there is a price to pay for ultra cheap ammo. If you shoot A LOT, it may well be worth having a 'sacrificial' upper or barrel for practice. Also, the cheap bi-metal makes great stash ammo, since you know it goes bang... YMMV bobcat
It is as I have always said about the AR platform system.... if your rifle will shoot it fine, but have excellent quality for any serious work. A stoppage can cost me my life at the wrong time, and I want dependability ...period.
Personally I don't use steel cases at all. I use reloads (brass) for practice/ training and save the good stuff for a rainy day. If you use steel better have spare parts laying around like extractors and any other surface that comes in contact with the steel case. It does not take a rocket scientist to figure out that steel against steel will wear faster than steel against brass.
All the testing they talk about is wonderful. However long term empirical evidence is worthy. I am a range officer at a large municipal / public range in south Florida. I see daily, many dozens of AR .223 rifles in action, firing many thousands of rounds. Of all the stoppages, failures to extract / eject, the primary cause is steel cased ammo. We keep steel rods at the range to clear such failures. My observations are not for a few AR rifles, but hundreds and hundreds of them. Steel case ammo might be fine for practice, but I advise that high quality brass cased US made ammo be used for ANY serious purpose.
Funny, My AR runs every one of these ammo's flawlessly
maybe its not the weapon, but the operator? or how the operator maintains his weapon?, hey its just my observation with what ive got
Im not saying that there might be "dirty" ammo, or that some may wear the weapon, or parts of it quicker, there again its how the operator maintains the weapon. Or how its built, I build em myself
any good operator has spare parts on hand , and knows how to field strip and change what may wear, or how to clean the weapon thru a battery of use.
I really don't know what to say, MY AR isn't finiky , or maybe its because I know what im doing to keep it running?
