IMHO...You can't go wrong with a muzzy head. I shoot a 3 bld 100gr. I would try the 4 bld, but I have a bunch of the 3s already. A friend of mine shoots the 4 bld head you are talking about. He killed a buck last year that just hoped 2 times after the shot and stood there. He bled out so fast that my friend was going to shot him again but it was all over before he could reload.
