RE: 2 Blade Rage Penetration
Well, first of all we got a couple possibilities working here. One, and a it's a cardinal rule of bowhunting, "What you think you saw is NOT always so". In my 38 years of bowhunting I have a couple real glaring examples. Bizzare stuff happens. The only way to know for sure is when the deer is recovered.
The second thing, I got to ask... what poundage are you shooting. What is your arrow weight, speed and/or K.E? I ask because I see it so often that people push the envelope while using mechanicals. Someone tells them it's more than enough and they take it as fact which isn't always true. Answer those questions and we'll have a better picture.
Three: Pass throughs, although the norm with todays equipement if properly set up, are not a given.
