I'm shooting 125 muzzy 4-blades. (total arrow about 455 with 3" vanes) I've taken several deer with shotgun, but although I've bow hunted several years I've never 'hit it hard' or shot a deer with bow...until friday. It was my last chance before I went back to college. A nice 4 point presented a broadside shot at dusk. It was a meat or no meat situation so I took the shot. At 55yards in an open field I hit about 2" higher than I should've. He turned and run directly away from me and I could see that my arrow only went in 4-5"!!!!!! Did I have the misfortune of squarely hitting a rib or is this normal for long shots. (I shoot a 60# Feathermax (IBO#310) so I *guess* that I'm sending 455gr at 235fps) It wasn't a nice hollow "thump" but neither was there a "snap" quality to the sound. Should I continue on or move down to a 100 cut-on-impact? This kind of shot (open field 40-50y) will likely present itself again because the of area and way I hunt. I picked 125s so I'd have a nice FOC (it was something between 10-11) and 4 blade cause I honestyly never thought penetration would be an issue with my setup. Now I'm thinking it may be time to re-evaluate things.
