243 barrel life

No! Nothing will make up for the amount of powder burned for a given bore size. The best you can do is get the longest barrel you can with out paying extra. Take 1.5 to 2 inches off the chamber end and 3/4 inch off the muzzle end when the group size opens beyond acceptable levels. First time shoot it in just blued second time after you see it still shoots nitride it or get the bore and chamber hard chromed. Competition barrels turn into varmint barrels this way for me.

If you want to compete with it the price of a new barrel and spinning it up is the cost of competition. In competition and heavy varmint cycles barrels are like car tires just something you need to replace all the time if you want to or not!

I know that when barrels are made to be chrome lined, they cut (or button) the rifling to a different size to allow for the application of the hard chrome. On the barrels you had hard chromed, did you notice any differences in pressure? Because the hard chrome is never applied uniformly to the interior of the bore, I wonder if the bore is able to be honed to a uniform I.D. after the hard chrome is applied. Maybe you can elaborate on the success of having your barrels hard chromed?
