I often use a different point of aim. Especially if I'm having trouble breaking shots on the center of the animal.
Truly a mental thing, but as Yogi Berra once said - "90% of this game is half-mental"!
It does work but really isn't any easier than shooting dead on.
You still have the break the shot JUST RIGHT.
My feeling is that this often helps me to shoot at a particular spot - something I find is more difficult for me when I try to shoot a bullet hit or paint fleck on an animal.
The POA's I use do breed consistency for me.
I use it with pretty good success on all of the animals EXCEPT the chickens.
Those little critters have such an irregular shape, the different POA doesn't help me as much.
On the Pigs and Rams, I usually hold on the back line of the animal and come down on my sights enough to produce a dead center hit.
On turkeys, I hold on the leg and come up 1.75 MOA.
On those pesky chickens, I have mixed results, but when I do, I hold on that little hump on the back and come down a minute or so.
This technique really isn't any different than holding a six o'clock POA on a bullseye target.
Beware of a few things - you really have to be honest with yourself on calls.
You can sometimes find yourself hitting high even though you thought you
"were about right".
Another pitfall is adjusting for conditions. You have to think a little more about what you want to do with your windage and elevation knobs with this technique.
That said, it doesn't hurt a darn thing to try it out.
Try comparisons on your range (not in a match!) between the different POA's.
I do this from time to time at 100 yards using a reduced size paper target.
This gives me more accurate feedback than dry-firing and the hits are easy to see.
When you're warming up for the match and using this technique, be darn sure to get a good DEAD ON zero so your adjustments will connect in the right spot!
