Whats the barrel life of 300wsm?

[tikka]

Would like to know what is the barrel life of a Browning A-Bolt 300wsm mk1?.
It used to shoot .5" @ 100m out of the box but now 2100 rounds latter its opened up to 1.5"
Not good for longer range hunting

Think you have answered your own question.

My first match 300 WSM got 2300 and was opening up. Being rebarreled now.
