Any info on buckshot, and T shot danger ranges? I live in an area with 5-20 acre parcels, heavily wooded, nearest house around 300 yards away. So the shotgun is my go to weapon if I need to go outside to investigate something.

From:

http://wethearmed.com/shotguns/how-far-will-lead-shot-travel/"Journee's Formula" for estimating maximum shot travel:

Lead shot size diameter in inches, (expressed as a decimal), multiplied by 2200 gives the maximum potential distance in yards.

To convert SAMMI voluntary numerical shot sizes to decimal, subtract shot size from 17.

Example: 17 - 6 (shot size) = 11 Move decimal two places to the left .11"

SAMMI #6 lead shot .11 x 2200 = 242 Yards

Federal 00B -measured, .325 x 2200 = 715 yards
