I dont know how much poundage your shooting, but my son shooting 37# with a 75gr muzzy put a 4pt buck 130# field dress
in the freezer. He shot a little to the right at 18yrd this little
fixed blade head went through the shoulder plate and penetrated
both lungs but did not come out the other side I think highly of
muzzys now, at least the little 75gr head.
