Well, got the last two bridge chucks this morning. At least I hope it's the last two. We'll see what the game cam says. Anyways, these 55 grain Hornady V-Max bullets are devastating. Pretty much just two gut piles.
Now if there are no more left, I can pour some concrete slurry down the holes and hope it's enough to stabilize stuff. It looks like I might have to pour some thick concrete pads around the bridge at both stream banks, I had halfass poured a couple of inches for about a foot around where the bridge meets the bank, but these guys just burrowed underneath and out. Little bastards.
There's a couple burrowing under a big elm tree by the house, and I'll need to get them with the shotgun and BBs since my shot is right in line with the one neighbor's house.
