Dude, no recalibration needed. Maybe it was just buck fever that screwed your head up in the moment. Know your arc. If you can see it and the gap is clear, you can shoot it.
Either weapon, I like to see how close I can get. When hunting with a gun it's always a muzzleloader. I've taken deer at 180 yards with it but for the past four seasons every deer I have taken with my ML has been within bow range. I have taken deer at 15 and 10 yards this year (both on the ground) with my ML. I just got busted this past Friday by 3 does at 15 yards. They saw "something" on the ground but I won that battle and just had to wait for them to continue on (head behind a tree, etc) so I could move to take the shot. As they proceeded onward, a gust of wind came from the wrong direction and they were gone like lightening!
Win or lose, nothing gets your heart pumping at 200 yards like that.
