I truly believe archers should have (within reason) the choice to choose whatever product they think will perform the best with their given hunting style, setup, and ability and therefore applaud the fact that expandables have been legalized.
But I do question this attitude that somehow mechanicals are better on marginal shots? I can understand how a bigger entrance, with possibly more blood, bigger swathe MAY increase the chances of cutting something lethal on a certain percentage of shots that strike soft tissue and liver/gut hits etc. But what about the other percentage that go the other way, And result in significant contact with bone? Wouldn't the benefit of a stronger bladed broadhead be more desirable in that situation.
I really wanted to shoot an animal with an expandable this year for comparison. My quickest kill with a fixed blade is a estimated 2-3 seconds. both elk this year were combined well under 30 seconds. ( this is using "crash time", Not when I walked up. I still give elk a bit, to make sure I wasn't mistaking other elk "crashing" which has burned me in the past.)And the cow was what I consider a marginal hit. Does the extra cutting diameter make that big of a difference on "perfect" hits?
