Stealthy,
I didn't pull the arrow out. It was completely inside the deer's cavity (broken off, about 8 inches plus head). I didn't yank it through entrails either. Took it out carefully. The entry hole was small and round.
My bow is a Browning Mirage SX set at 65lbs. I"m shooting 60/75 Beeman carbons (not sure of weight?) and 100 grain heads.
I'm not trying to make a negative statement on mechanicals. I really don't have the expertise to comment. I know you can have poor results with either fixed or mechanical. I'm just curious how a fixed head might have reacted under similar conditions.
I might just try to fill my second tag with my Bob Lee Stick longbow and Simmons Sharks and avoid the whole debate in my mind
