I found a couple of boxes and was thinking about using them for blackies. I read a pile of reviews and the gist I am getting is that they are not a good choice on deer size game but critters such as elk, bear, moose it's a good choice. I am thinking that the 130 will certainly give me adequate expansion with pass through on blackies. Should I go to the 165's? If I should then I'll have to stick with my Nosler 180's since I can't find 165 TSX's anywhere. I am looking for good expansion with a clean pass through. Never shot these let alone used them on game.
