"...Full metal are no-no's for hunting..." Military ball for sure. However, commercial FMJ's are made for hide hunting. They're not the same thing.
"...planning on hunting in woods..." Wiley will see or smell you. Do some research on Wiley's habits.
"...At range..." What's that to you? You have to sight in with the ammo you intend using and know where the bullet will be at any given range. Sighted in at 50 yards, a 158 grain Winchester SP will drop 2.4" at 100. 9.1" at 150. Sight in the 2.4" high at 100 with a 158 grain bullet and you'll be ok out to that distance. It's the bullet weight that matters though.
