What is the minimum safe rifle hunting distance away from houses and roads you would hunt in a tree stand approximately 8 ft off the ground with a .308? I have hunted the same area the past four years with a .308 but it was in pretty dense timber that led to a swamp. Now having to hunt a different area of open crops with only a thin treeline. Also the stand had to be set up with a house (who's owner doesn't care) about 200 yards behind it. Just concerned about overtravel and ricochet. Also have a 30-30 I was debating using in this stand.
