I'd guess the barrel should be good for hunting accuracy to around 1000-1200 rounds and this is about what Kirby has said before. Since it's 32" you could have it set back and rechambered and go at it again with the same barrel.
The ballistics are comparable with whats been posted many times on here about the 7mm AM. 200 grain Wildcats at around 3200 fps and 160 Accubonds at around 3500-3600 fps. I normally keep the Wildcats a little under 3200 to keep them together and I run the 160 Accubonds at 3550 fps.
