Here's a useful tool from 6mm-BR a Barrel Life Calculator. Don't expect it to give you an exact to the bullet estimate of when your barrel will be shot out but it will give you a starting point.
There are a lot of other things to consider like alloys and what you consider to be poor accuracy too. In my experience it give low estimates but is a good comparison tool for lets say deciding what calibre to go for.
NB: The powder heat potential list is in the comment in the cell you enter the heat potential in.
