I currently use the 3-blade Muzzy 100 grain broadhead. I've been wondering how much speed would be gained by going to the 75 grain. The reason for this is that I'd like to shoot a little flatter and maybe be able to use just one pin out to 30 yards. I only hunt turkey and whitetail with my bow, so I'm not worried about carrying enough KE to punch through the shoulder of a moose. Is this one way to achieve my goal? If not, what are some other options?
