I wonder out of the THOUSANDS they fired between cleanings, if they cleaned a rifle after a few hundred rounds were fire like 99% of you and myself included do, how many steel case jams would have been present?
Im not bashing brass, but to refuse to shoot steel case because it "wears a barrel faster" or "I saw 2 rifles jam" is dumb. For a precision gun, I dont run brass... but for my AR15... steel all day.
If you even will shoot 10,000 rounds out of the rifle, lets do quick math.
10,000 rounds of wolf, will cost you $2000.
12,000 rounds of American eagle brass will cost you $3000
A 16" .223 WYLDE barrel will cost you $63.99
So you could spend $2464, get a barrel and 12,000 rounds of wolf and will most likely not burn up your 1st barrel, because you wont, 1) shoot that ammo in 1 day, 2) you'll clean between shootings, or atleast you should.
Dont shoot steel if you dont want to, thats perfectly fine.. but to blackball it over something you saw on the internet... is pretty dumb IMO.
