I think you are doing fine and just keep up the practicing. Try this little trick I learned many years ago. Take one shot a day or one in the morning and another 5 hours later. When you practice really hard you are out shooting maybe 10-20 shots all within a half hour or less. By switching to only taking one shot per day you are puttinig 100% emphasis on that one very shot and it counts! It's like the real thing being out in the woods...you only get one shot! So make it count.

Try it for a week and see how you do. You might be surprised that your one shot a day is placing where you want it to!
