Stainless is soft. It is generally more accurate but with a shorter life. Chrome not only is corrosion resistant, but is very hard, giving it a longer life. That's a new one on me . It's generally true. I would say to think of it in relative terms: you wouldn't want to use a match stainless barrel as a burner barrel, and you wouldn't hope to get great consistency out of an inconsistent process like chrome lining. While they are two methods of making barrels intended for different purposes, I would go out on a limb and say that most shooters either couldn't tell the difference when shooting them, or their shooting schedules don't demand such an advantage in durability or accuracy to tell the difference. |

What's the round count expectancy of a Noveske or Krieger match barrel? What's the round count expectancy of an rack grade Colt barrel? |

Most button rifled stainless barrels are only about 20-24 Rockwell C. Hammer forged stainless barrels can be 35RC or a little harder for 415 stainless. Hard Chrome is 60-65RC or a little more.
Brinnell hardness rating for 304 stainless is 250 vs 1000 Brinnell for Hard Chrome. |
