I will be hunting Elk in 10 days and I am concerned with my the broadhead flight I am getting out of my 125Gr. Muzzy (3 blade). I use 90 Grain muzzy (4 blade) for deer and they work very well. My question is will they be enough for Elk? The cutting area is only 1" . I shoot a Mathews with 29" Blackhawk Vapor carbon arrows at 68lb. with a drop away rest.
