Barrel wear - velocity

There is a lot of discussion regarding the premature wear of barrels where high velocty rounds are concerned. At what sort of velocities is barrel wear accelerated? Are there any ratios of twist times velocity that have ever been worked out.
I am sure there are many variables, I would be interested what the reloaders here think.
 
Interesting and I agree: pressure (heat) is the bugger-boo of throat wear. I disagree with his assumption that 10000 rounds of .22LR will wear out a barrel. I have shot more than that from my Brno#2 over the last 28 years and it will still shoot sub MOA at 100M when the wind gods smile. Shoots bug holes at 25M... and Lord knows how many rounds it saw in the 25 years before I bought it. Twenty-twos that are cleaned frequently are rodded to death, not shot out.~Muir
 
That is totally rubbish about 22lr.Just think of all the old bsa and other target 22 that are still in use as club rifles at ranges and still win competitions
