Hammer Forged vs Button vs Cut

[Forgetful Coyote]

Obviously CHF can produce some awesome tubes. Hammer forged barrels from Krupp steel seem especially high regarded in Europe(Blaser, Heym, etc). Sako TRG 22/42 use CHF barrels, also the FN SPR. Lots of AR manufacturers use it. I know CHF's main advantage is big production volume, but specifically regarding precision rifle barrels, does CHF have a higher failure rate than button or single point cut? As far as what does and doesnt pass inspection/make it through QC? Ie is it capable of making Benchrest accurate barrels at as high of a rate as someone like Bartlein, if thats what the manufacturer was going for? Ive read that atleast in the past, HK would have to straighten many of the barrels that came out of the machine, and that the ones that came out straight were set aside for use in the PSG-1, etc G3-based precision rifles.

An interesting vid, specifically Mr Anschutz's comments on how CHF didnt work out for them and button rifling ended up producing more accurate barrels for them:

Seems like you answered your own question. There are good barrels made by good barrel makers, then there is everybody else when looking for benchrest accuracy.

Agree with Dave. Any idea how many rimfire Olympians shoot hammer-forged? How many machinegun manufacturers use cut-rifled tubes?

Different manufacturing technique for different results.
