NDOW reports that 73% of bulls in those areas were 6 point or better in 2014. I personally don't hunt anything thiking about what it might score but that's just me. If it looks big to me I'm shooting. I think 330 would bo quite doable. I'm sure you are a better bow hunter that I am. I have only hunted deer with a bow but have not yet gotten one in about 10 years. I do know that a lot of bulls in NV have tines broken off during the late rifle hunts because there are a lot of bulls, Nevada has a pretty high bull to cow ratio.
I definately would not eat a bull elk tag for NV they are really tough to draw and it would probably be more that 10 years especially since you have to wait 5 years to apply again even if you aren't successful.
Good luck to you and let us know what you see.
