I've used NBT's on a lot of game and out of a lot of cals and most of them have a lot of speed to them. I sure don't wait till a critter gets to a point where the bullets going Sub 3K till I drop the hammer.
Close range, and a lot of speed then a lot of meat will get rearranged and that's fine with me cause I like my critters turfed quickly.
Bottom line, load em up and light the torch.

I love it.....and agree 100% !
