I spend some time clearing field in a wooded area, from time to time. While I never have encountered any boar, snakes, or threatening wild animals, I change from HPs to FMJs for SD when working the property. IMO, it helps if you give the animals a fair chance to retreat. Make some noise, be observant and alert, and move slowly, till you're sure all the critters have found someplace better to be for the day...
