Thread: Does a bull barrel help reduce throat erosion?

A major factor in throat erosion is heat, obviously.

There is an argument that a heavier barrel resists throat erosion better as its harder to heat it (the throat) up to the same temps as a lighter barrel; before the heat is wicked away to the remainder of the barrel.

As always it will depend on how its treated, though I have no doubt if a person took a light contour barrel and a heavy one, and fired one shot down it every two minutes or something till the throat was shot out - I think the heavy barrel would do better as it has more mass to wick the heat away from the throat area.
