RE: Appropiate Bullet Weight
The 270 isn't a woodchuck round, but it will give you some "good" practise with your deer rifle.
I'd load 130 grain bullets sighting in at 200 yards. Then shoot that "one load" for everything from deer on down. You will learn where ithits at different ranges, and become a much "better" game shot!
Switching bullet weights just makes everything a lot more complicated than it needs to be.
