accuracy with recurve/longbow?

[Muskeez]

Looking to improve my accuracy and distance also. What's the best way? I was thinking I should shoot from 10 yds until I get 10 in a row in the 6" circle, then back up two steps and do the same, and etc. Does this make sense? Anyone have a better way? I shoot a 55# recurve and "nontraditional" carbon #400 arrows with 125 grn Thunderheads. I was shooting instictively and have shot a few deer that way but recently switched to sighting down the arrow which seems to have improved my accuracy a little. Any comments? I'm obviously not a purest at this traditional bow hunting but really like the added challenge and reward of shooting deer with a recurve. So far I've limited myself to 20 yds. Thanks for any helpful ideas.
