Well i used to think they were good for about 200 shots or so. Here lately i have changed how i make them, and the flash holes are now longer than what i used to make them. Currently i am using a vent liner that has over 200 shots through it, and the flash hole has eroded to only 0.030", after being made with a # 70 drill, which is 0.028". This vent liner could last 400 shots?
From what i have read, if you are looking for longevity, your best bet is the Lehigh vent liner.
