First let me say I very seldom shoot across the yards unless I'm shooting in a bow I just made. I almost totally stump shoot the fields and woods. If you think your good take a walk with a judio. You might come back home with a different thought.
I practice 20,25 even 30 some times. I never think yardages and if you shoot instintive you sould'nt either. You want your hand-eye-brain to do it for you. I may prictice that far but set up buck and gobbler hunting to where my shoots are all 10 to15 depending on cover,time direction of sun. The sun kills the best set ups. Even a good place to set flat off the ground or off milk creates when I have the cover. But I never make them over 18 .20 at the edge of my zone. My favoret is around 12. Not many people get inside of 20 yards of mature bucks even out of a tree. I've tota;lly ground hunted since 06 after 2 strokes. Could'nt hunt angain untill 08.
Remember your not at a shoot competeing with compounder's just the buck, deer in most of you alls thought. BUCKS in my thoughts. I set up all my sites for buck and gobblers the same. Where they've went passed me. Like this their focus is to their front already gone past alowing for you to draw and shoot. With out them seeing you.
Forget those broad side shots likely you'll be see as you draw at the lease they know somethings up. Broadside shots are totally imposable with gobblers off the ground. You don't have a compound to where you can DRAW AND HOLD when the animal go's behind a tree. Instinve shooting all done in one motion (MAYBE HOLD A SECOND AT BEST) if you wait for the buck,gobbler to come out from behind the tree it's hard to pick a spot draw hold while it's still behind the tree.
I'm sure you've all did this. When the buck,gobbler came from behind the tree you shot high or over him. Thats because when he came out you had to hurryed. Your eye went to the most prononced thing the line of his back. The spot you picked and shot high or over him.
