too bad they didn't use DPMS rifles ... maybe they could have put that issue to rest as wellSaw this very interesting test of 10,000 rounds each of Federal FMJ, Brown Bear, Wolf and Tula in four identical Bushmasters. Well executed test, quite detailed, a real torture test. Thought I'd make a post here for anyone who hasn't seen it yet.
Well worth the read.

... serious accuracy issues were noted with two carbines ...
No way two of four factory rifles should have such serious assembly issues. This is inexcusable and embarrassing for Bushmaster. I have to admit the rifles performed well after they were assembled properly. You'd think assemblers at Ilion would be trained better.... Barrel nuts were torqued to inconsistent values: two had been torqued to approximately 5 ft/lbs, while the other two had been torqued within the appropriate range of 30-80 ft/lbs...
5lb torque on the barrel nut? Surprised it didn't just wiggle loose off the rifle as it was fired, or worse.No way two of four factory rifles should have such serious assembly issues.

I am sure BILLT is going to say "I told ya'll so". I still think steel is acceptable if you are not competing. A lot of AR's will fire them without a hiccup.That would be interesting but I wonder if it would have done any better than chrome lined. What was fortunate is that the BM/Tula problem got a CHF barrel in the test. And interesting that CHF didn't improve barrel life.
I'll continue firing steel case since I have a lot but there is a hidden expense especially if you love to do repeated mag dumps.
True, true! And on a rifle that harder to rebarrel the extra barrel wear is something to consider when buying ammo. The AR's ease of replacement makes the decision easier.I am sure BILLT is going to say "I told ya'll so". I still think steel is acceptable if you are not competing.
