.308 lapua brass life your experience

That's my load too!!! Very accurate! It's a light load, so if you're neck sizing and annealing, I'd expect your brass to last a very long time...you'll probably wear your barrel out with one hundred pieces.
Good luck!!
 
No experience with Lapua in particular, but...

I think there are too many variables to get a real answer. It's going to depend on how hot your load is, your reloading procedure (FL, bump, or neck), your chamber dimensions, and how often you anneal. And when you consider your brass worn out. And whether it's in a bolt or semi. And maybe the position of the moon.

You forgot to add sun spots and whether or not you're getting enough pussy.
