Hammer Forged Barrel - Pros and Cons?

How does one measure this "stress" before and after it is relieved? Can it be seen in the metal structure ? Is it with a strain gage of some sort? Thanks Jeff
 
I guess shoot it till it warms up more and more and obsverve how much does the group patern opens up? 25 to 30 shots should do as I can't think of many competitions that shoots much more than that ( except the Norwegian mad minute!).

For butch , 4 leaf clovers. I will try to dig out one of the test target.
:P

Well, for a multitude of reasons, including wrong twist, length, weight, caliber. I want my next Howa to be 6mmBR, but they don't offer that, so the barrel has to be replaced.

Please don't automatically associate the TYPE of manufacture with the QUALITY of the product. It is entirely possible to make crappy (or excellent) button or cut-rifled barrels, just as much as it is to have variable quality in a hammer forged barrel, or any other product for that matter. Is HF technology so primitive that even at its best, it is simply not possible to produce a barrel that is superior to the "crude" barrel on stock guns? We will never know, since there is no one that I know of that has tried making a "high end" HF barrel. It could be said that no has tried to make the high end HF barrel because of some perceived acknowledment that HF barrels can never measure up to other technologies. But is it that, or possibly that HF barrels manufacture is suited to large deep-pocket companies who have little interest in niche markets, such as BR barrels? Not saying what is correct, just asking the question.

Sako makes the TRG-XX series of rifles, all of which use hammer forged barrels. These are not BR rifles, but few would say the barrel is "crude".



Actually, I am seeing more and more questioning of expensive custom actions vs tuned up factory actions. The custom actions sure look and feel nice though.

Thats because a hammer forging machine is very expensive. The small custom barrelsmith have much cheaper cut rifling machines - most of them are Prat+Whitney and many many decades old or much cheaper button rifling machines.

Here in europe we use more hammer forged barrels because there are enough companys who offer them.

Well made there is no difference if a barrel blank is hammer forged, cut or buttoned but a hammer forged barrel blank can be made within much lower tolerances and so the custom gunsmith safe a lot of lapping and calibrating time.

The only big dissadvantage at hammer forging is the twist. It can`t be changed - it`s fixed by the hammer mandrel and this mandrel is very expensive. Thats a big benefit for cut and buttoned.

Your commercials become tiring. If you really believe in your barrels, tell your company to invest in the proper tooling to make barrels in the requisite calibers and twists and demonstrate their superiority at the highest levels of competition. Heck, you can start with European benchrest. Just think of the advertising value. Understand something, we are impressed with results. Now get busy and create some.
 
When setting back HF barrels I've only ever been able to get a 1/2" MOA at best on a heavy barrel with some ok consistency. You'll get tighter groups but nothing to count on.

Most factory HF barrels have poor machining consistency when threading and chambering. I've seen many barrels through the scope that have one half of the lands cut off from the throat area from an out of round chamber. 0.005-0.010" run-out between threads and chamber.

Some of them will shoot if they are machined properly, but take 100 HF barrels vs 100 cut or button barrels and you will never beat the Cut or button barrels overall.

..... There I go trying to be serious when i just see guys are being sarcastic the last page or so.... Oh well.

Well there's someone obviously affiliated with a company that uses hammer forged barrels ;)

Hammer forged barrels will never be up to par with high quality button or cut rifled custom barrels...EVER. There's just no way that beating a piece of metal around a stick can make a barrel with benchrest accuracy.

I appreciate our custom barrel industry more than anyone save their actual owners, but we should not forget that an item like this Cameo Gold Eagle, below, - far more intricate than a barrel’s rifling, is struck in a manner that most closely would mimic cold hammer forging. You could theoretically roll on the image like newspapers are printed or barrels are labeled, and that would resemble button rifling. Likewise you could scrape away everythg that is surplusage, like chiseling a sculpture, or a using a stock duplicator, and that method would resemble cut rifling. Which method would you suppose results in most perfect metallic impression/image?

I’m glad that hammer forging hasn’t overrun a cottage industry, but product inferiority is not the reason in my opinion. Endlessly differing barrel requests are the reason, along with high equipment costs, and the fact that they would shoot no better.

Minting coins is one thing using a particular material, Making Rifles Barrels is another, using a differing type of material of a differing hardness.
The "Results" in rifle barrel making have spoken for themselves for years (IMO)
