I'm relatively new to hunting (2 years) and just recently bought a rifle. In the past I've borrowed, and absolutely could not do that again. Anyway, I've got a .30-06 and I'm wondering what grain and bullet type would you recommend for whitetail deer in an area that's thick woods with few openings and almost every shot is under 100 yards? I'm thinking 150 grain, but I have no idea what type of bullet.
