Good question...also is it the heat cycles or is it the friction caused by the bullet that causes a barrel to lose its life? Probably a combination of both?

CHF for me. And to be specific, a CHF DD lightweight (.625"approx) profile 14.5" mid-gas barrel.They should be out in the next 3 weeks.

A fellow at Sabre Defence told me they expect their milspec chrome lined M4 barrels to run 35,000 rounds. And those are button rifled, not hammer forged.
I wonder what the true barrel life is for a Noveske with a hammer forged barrel made from M249 barrel steel. 100,000 rounds? Should be the same for a Centurion barrel.
I'm not sure how a hammer forged barrel outlasts a standard barrel if they are both chrome lined. The heat and friction will eventually wear away the chrome lining, so isn't the hardness of the chrome the relevant component of barrel life?
As the chrome is worn away the rifling has a less consistent contact with the bullet and you get a degradation is accuracy. The rifle with still work the groups just open up?
I also don't understand how chrome lining that is twice as think (Noveske) would make a difference. If the rounds wear the chrome lining a measurement of X wouldn't both barrel standard chrome lined and double thickness chrome lined now have the same amount worn? They had to have the same interior dimensions to to start with and in both cases the bullet wears the same amount of chrome, so the interior diameter would be the same...

I'm glad i got a CHF barrel. I dont shoot a lot either but it's good to know it will last a very long time and they can handle really high volume shooting.
