"Would I have taken the shot"
Last fall I actually did, with tragic results. The doe was looking right at me about 12-15yds. I wanted meet for my freezer and she was about to bolt so I took the shot, bang flop.

Then she got up and ran off never to be seen again.[:@] My brother was with me (I'm glad I had a witness to help me analys what happened) and we both thought it was a good shot, placement wise. I was shooting 110grs APP with 300gr Barnes Expander MZ out of my CVA Wolf. Never found any blood or hair and we followed where she ran for about half a mile with no sign. I myself must take the fault becuase all the other variables in that moment were as they should be and yet some thing went a foul. In my situation I take credit as I was very new to muzzleloading at the time. This year though I have put more time at the range behind the ole Wolf and topped her off with a red dot. I now know with out a doubt that inside of 50yds that barnes MZ will go right where the red dot is. Last week I had another oportunity with a doe she came across a field striaght at me but I waited and at 20yds she was broadside that's when i pulled the trigger for a perfect Bang/Flop.
Would I take the stright on shot again? Probably but I think it depends on the circumstances if that doe last year hadn't seen me she probably would have eventualy provided me a broadside shot much more ideal IMHO. But I am definitely an advocate of following your conscience, like some one else already said, a shot that I am comfortable taking may not be comfortable for another to take. Work within your conscience and you will not have to ever second guess yourself.
So I congragualate you for following your conscience at that moment even if knowing what you know now you would do differently.
