RE: Slowing your hunting arrow down?
I agree that speed is overrated for hunting. Yes...its nice, but certainly not needed, especially when the majority of shots are < 30yds. I shoot a 530gr arrow @ 240fps....I get passthroughs 90+% of the time. If I dont...its typically becasue I made a bad shot like into the knuckle joint or something. Keep in mind, I shot Muzzy's for years, then went to Magnus about 5-6 yrs ago. Both have performed excellent for me. Only thing I can think for you is that the BH's you've been using are just eating up tons of energy. Even so....its still puzzling why you haven't gotten more passthroughs though, you've hit your deer well. No major bone involved - should be blowing right through imo. ? Good luck.
SA - you are right, ArthurP is probably right. [8D]Think about the older bows, or even the guys who shoot recurves with a good broadhead (and heavy arrow) that still get passthroughs....gotta be something to it.
