could some one explain to me why i should pay more money for a hammer forged barrel when once the chrome lining has been applied the barrel life is the same as a standard barrel, also explain why i should pay more for something that is produced at a lower cost compared other manufacturing processes. and if this has been discussed before please direct me to the threads, search just gives me a blank page or the try again in 30 seconds message
Your assumption is incorrect. CHF barrels have a far greater life expectancy than other types, chrome lining nothwithstanding.
Tommy, I asked the same question about why the chf are more robust when it comes to hard use and a battle gun & I also had some questions about the mandrells use and the tooling process. Hopefully, someone will share the same link as it was quite informative.
Not sure I can 100% wrap my head around the entire deal but i think it really boils down to your shooting style and buying habits. I have always tried to be a buy once, cry once money spender (when I can). If you are going to shoot 500-1000 rounds a year, I'm not sure you could really tell the difference, but you aren't talking a huge difference to get the better tube. If you run the gun hard, then buying the best bbl is the only way to go as you are going to spend a ton more in ammo.
You can actually apply your question to most of the AR's components / add ons & you just got to roll with your wallet size and make a decision based on saving to get the better upgrade or settling.
example:I really wanted an AAC or Surefire suppressor for my sbr but got a crazy deal on phantom from my class iii compadre. I could not justify paying what was over double with the budget I had at the time. I don't like the weight of the can I have but know I'll be able to swing a top shelf can down the road.
For most everyday shooters, ones that shoot every now and then, 2000 rounds a year, etc, the standard barrel will do just fine. The steel structure is more dense, providing more life for higher round, full auto, shooting. So, if one has the funds, why not go with the hammer forged barrel.
Here are a few threads on the subject:

Hope this helps.
i base it on the thread where pat rogers talks about loaner rifle #14 having 35,000+ rnds through it with out serious diminished accuracy.Quote:

I should qualify that most my shooting is at 3-gun matches with some practice in between matches (5-6,000 rnds a year) so with a life expectancy of 10-15,000 rnds from a BM barrel,it would only last 3 years at that rate.
i would like to replace my present BM barrel with a more durable one with a 1-7 so that i have greater reach with heavier rounds. i shoot 69 grain almost exclusively,
Ask Gotm4 aka Robb about some of the CHF barrels throats he has borescoped and how they compare to standard barrels.
Chrome lining will eventually erode away at the throat until its down to bare steel that is why Hammer forged barrel really starts to be a benefit once it is down to the bare steel compared to a none hammer forged barrel. Hammer forged barrels started in Germany in wwII The MG-34 and MG-42 would burn up barrels in a hot fast minute literally. Hammer forged barrels can be made fast some hammer forged barrels the chamber and the throat will be formed at the same time the rifling is formed this allows VERY consistent chamber and throat has they are not cut out and not subject to reamer wear. Hammer forged machines COST Million's so the cost of the machine has to be payed for. Does every body need hammer forged barrels NO only if your goal is to have the longest barrel life possible should some one consider it.Quote:

I would prefer a precision stainless upper w/ dedicated hunting optics for that application.

If you're shooting more than 6K+ rounds per 12months IMHO you should have a hammer forged barrel. Sure other barrels will still serve you well but the hammer forged will serve you even better. In my experience in seeing lots and lots of barrels from all manufacturers is that hammer forged chrome lined barrels wear the longest. Wear occurs fastest in stainless barrels followed by carbon steel non-chrome lined barrels, followed by non-hammer forged chrome barrels, and followed by hammer forged chrome lined barrels using 11595-E lasting the longest. Hammer forging is the VERY best way to make a gun barrel. Coincidently the companies using 11595-E barrel steel (and can prove it) also know something about having the right sized gas ports....kinda comes with the territory.
Are the DD barrels 11595E? I've inquired directly to Daniel Defense without answer.Quote:
