Question #1 - No the gunis crap. Don't touch it you don't want any of it on you. Look at a Savage, Weatherby Vangaurd, Tikka,Stevens, or Mossberg before you look at that thing again.

Question #2 - The 300 will be great for dense brush and open area but not needed. A 270 or 30-06 wil be just as good in brush and just as flat in the open without the magnum recoil and it is a lot more recoil.
