If you've ever shot a deer with an arrow.......you kinda lose credibility when you argue that the exit hole is MORE important than the entry hole. Without the entry hole.....you stand NO CHANCE of having an exit hole.
And.....unless your pass-thru percentage is 100%.......you lose on that argument, as well.
Give me a big entry hole.....and a well placed arrow....and I'll take my chances with an exit hole. A well-placed arrow doesn't always result in an exit hole.
