There's a certain distance that everyone has that "feel" for and I call it a "ZONE". Within that zone you "know" you can hit exactly what your shooting at. It sounds to me like that zone has found itself for you and it's within a 15 yd. radius. Go stump shooting and pick out stumps and clumps etc...and shoot them. After you get to the point where your always hitting them begin stepping off the distance "after" the shot. You will find that every time you pick out a shot that's within your zone your deadly. Contrary to popular belief, that's what traditional shooting is all about. Knowing your limits isn't a good way to put it in my mind. I would rather say knowing you kill zone. Once you establish that mental zone you will begin restraining yourself from shots at game until they come within that mental zone. I've never really understood why people think it's harder to kill a deer with traditional equipment. I think what's harder is to kill a deer at distances that either you want to shoot or that people with wheels and sights can shoot. I happen to shoot both types of equipment and I have stands that I carry a compound to because the chances are my shot will be about 10 yds. outside of my traditional kill zone and I am very comfortable shooting the compound out to 25 yds. There was a time that I felt only real men shot traditional equipment but when I started hunting for only good racks I figured out that there will be certain set ups that don't lend themselves to my traditional limitations. You need to make the choice of which is more important, the kill or the "way" you make the kill and then stick with the limitations you've placed on yourself and be content with the results.
