I keep seeing cold hammer forged chrome lined barrels.
Isn't the point of cold hammer forging to build a stronger barrel with a more precisely shaped bore and better rifling? If so wouldnt chrome lining it remove some of the acuracy from the barrel due to varying thicknesses of chrome when chroming a barrel? Perhaps melonite coating a CHF barrel due to the more even coating but not chrome. That seems to be defeating part of the purpose. The only reason I can think so far from what I have read is to do it for marketing/cleaning but not acuracy. Am I off base here? |

It was my understanding that cold hammer forging increases production and lowers long term manufacturing costs. Not that it produces the absolute best barrel. Just what I've read. Don't flame me if its wrong, although corrections or addtional info is welcome. |

I think hammer forging actually pounds the steel adound a mandrel to form the inside of the barrel and rifling rather than cut or button rifling. Its also I believe improves the metallurgy of the barrel. Anyone?? |

Barrels made this way are actually less expensive to manufacture than other methods although tooling costs are extremely expensive compared to other methods. Traditional rifling techniques are not known for their speed. CHF Barrels have been the recipient of a good marketing campaign. While a very good and durable barrel there are better choices in terms of accuracy. Chrome lining is done for corrosion resistance and definitely not for accuracy reasons. |
