OP, have you shot much with a timer?
Simply doing draws and single/multiple shots, on different targets, at different distances, under time, pays dividends in this regard.
On a silhouette, work from just drawing and hitting it fast, to drawing and hitting THE SPOT YOU WANT TO HIT fast.
But I agree with the other poster who said you did good (you killed it, right?).
I definitely need to work on spot shooting and spend more time with a timer. That mixed with time in the woods should lead to helping for the next time
To my mind, this is why hunting is important. I think the buck fever analogy is accurate. Visualization is important, but not an end all be all. I remember the first time I killed a hog with a knife. In my mind’s eye, I used my dominant hand to hold the knife. When the time and opportunity came, I had to use the other strong hand. Still worked, but the fight will very likely not be what you imagine.
At any rate, inquiring minds want to know, what did the 9mm do to the hog? Do you have sausage in the freezer?
