^^^^^^+1 55gr NBT is my go to coyote bullet in AR at 3100. A few years ago, while hunting coyotes, was also tasked w/culling whitetail does and feral hogs. Shot several 90-100# does w/the 55's plus a number of feral hogs (about same weight) and all but two hogs were DRT. Those two hogs were frontal shots between the eyes; saw the 2nd one splash at exact POA. Knocked the boar to his knees but he got up and was not recovered. I'm sure the bullet splashed and never entered brain cavity.
You should be fine w/the 60NBT's.
