Everybody needs to make their own numbers based on:
1) Their actual ammunition costs
2) Their personal rifle's barrel life, which of course is based on several variables in itself
3) What they do with/get for brass cases, and what % of their brass cases they recover
4) And more
But let's look at what they had in the article:
"Although ammunition prices are volatile, the prices of brass and steel remain similar to one another – that is, brass is generally more expensive...For this chart, brass ammunition was calculated at $130 per thousand higher than steel and replacement barrels at $250 apiece."
So they used $130 as the difference. The brass I sold was net me about $112 per 1,000. I figure that, on average, I recover 80% of the cases I get from firing brass ammo. That would be $90 per 1k that I get back from selling the brass, using actual numbers.
That puts the price difference as $40 per 1,000 which means that steel case ammo is not only inferior in performance, but it doesn't even save money once you account for premature barrel wear. Remember that the Federal barrel still had plenty of rounds to go before it would have worn out, and the steel case barrels were "shot out" at around 5,000. That means I would have go buy 1 or 2 replacement barrels while shooting all steel while buying 0 replacement barrels shooting brass case.
Using my numbers, I'd have to get at least 6,500 rounds out of the $250 barrel in order for steel case to be AS INEXPENSIVE as brass case...and then there is the case of the inferior performance of steel case on top of that!

What buffer does your rifle have? If it is factory then it is likely the same as your friend's Bushmaster. The difference is most likely the diameter of the gas port. A larger gas port has less trouble running the steel cased ammo since it will allow more gas into the action.
Yes, I like pretty ponies.
I was shooting with a friend today and he had a case stick in the chamber of his colt 6920. It was a 62 gr Herters. Took a couple of taps with a steel rod and hammer to get it out. Primer was flat, not sure if that would be a sign of over pressure or not. He's gonna scub the chamber and give it another go. He's never had trouble with Wolf...
Primers pop out if pressure is very high. Wolf has consistently proven to have a higher pressure so that is probably why he hasn't had a malfunction. A good tool to have on hand is one of those broken case extractors, not sure of the exact name.

Do you have some data that you can link to showing that?
This other LuckyGunner test pressure plots don't show that with Tula or Silver Bear....
