I’m curious as to the actual benefit in terms of longevity of the “double thickness” chrome lining on Noveske N4 barrels.
Essentially, what I’m wondering is at what sort of round count does a “normal” (Colt, for example) chrome lined bore have its chrome lining worn away at the throat? I’m not familiar with the actual thickness of barrel chrome linings vs. the amount of throat erosion necessary to make a barrel inaccurate, or even unsafe. I’m assuming that the chrome lining is completely eroded before the barrel’s effective life ends, although I may well be wrong about this.
For the guys out there knowledgeable in the technical aspects of barrel throat erosion, what benefit do you foresee in doubling the thickness of a bore’s chrome lining? Will it really double the useful life of the barrel?
I imagine that there are so many varibles that could come into play here that it would be hard to say. Rate of sustained fire, type of ammo used…
Noveske puts out good products and I am sure that at least some testing has been done on his part to make sure the claims made by the company are true.
