Comparing those Hard lined MG barrels to a high grade C-M or SS match grade rifle barrel is like comparing apples to oranges.
As has been mentioned, the MG is designed to lay down a withering spray of bullets without regard for precise accuracy, only rate of fire in the direction of the enemy.
A precision rifle, built properly, will place 5 or 10 shots into a dime sized group at 2-300 meters. Once the wear in the throat of the latter shows any significant wear,
the groups begin to open up a bit, and the discriminating shooter either rebarrels or sets the barrel back and rechambers [for a bit more life]
The take-off barrel would probably make the average hunter very happy for a lot of hunting seasons.
Really, the factors involved in barrel "wear" are complex and it is not fully understood, even yet, although metallurgists have a pretty fair idea.
The fact is, barrel life in the M60 or the M249 cannot be compared to that of a
precision rifle. Different materials, different standards of performance, and different circumstances entirely.
