Buckshot
Really what i was saying is it does take a abit more energy in order for a mechanical blade to work. if any one in here hits just the fore leg of a deer you can't expect to find it.The blades on a mechanical will possibly fold back in and fall out,a fixed blade coming back out the entrance is goin to do some damage a mechanical may not.
Any broad head placed in the wright spot will do the job .as far as my muzzy 75's flyin strait not a problem for me.But it takes at least 50 or more pounds of conetic energy to get the mechanical through a shoulder blade.Which is a shot that was miss placed in the firt place .Mine at 15 yards.
