Anyone shot out a nitrided barrel?

[Strop10]

How long have nitride barrels been available? Does any entity[ foreen guvmint,alfibit agincee, ect] use these? I'm kind of curious myself. I have chromed, steel and nitride and dont put enough lead down range to make an assesment. Unless the country comes to some deep shit or I become independently wealthy I'll never live long enough to wear out any of them. Then again, as the saying goes curiosity killed the cat,do I really want to know?

If you have enough ammo to burn out a barrel you also have enough money to replace the barrel. Or the whole dang rifle, probably several times over.

The general consensus in the benchrest/precision shooting world is: 'why in the world would you want to nitride a barrel?' They figure that barrels are consumable items, just like ammo. You shoot it until it quits shooting up to expectations, and then you replace it. Part of the reluctance to nitride barrels among that group is what happens if you get a stinker - a new, high-quality aftermarket barrel that doesn't shoot for s**t? You're already into it for $500 or more by the time it's chambered and threaded, and then you want to add additional cost for shipping and nitride treatment. Why bother?

On the BR forums you regularly see take-off name-brand barrels for sale with maybe 100-125 rounds through them. Those are the ones that don't shoot to standard.

For precision shooting barrels, it's often recommended to fire rounds to 'wear-in' and polish the bore, and remove those microscopic high spots, first. Then, run copper removal solution, neutralize, oil, then send in for nitride.

That way the QPQ process 'locks in' that bore condition, without those tiny cutter leftovers... and, it'll give you the feel whether it's a stinker prior to QPQ.
