Gap shooting isn't hard at all. For me, it's the best way to work on form as I can eliminate that variable by putting the tip of my arrow at a single spot and then focus on the expansion to release. If the tip of my arrow is at the same spot but my arrows are scattered, then clearly, it has nothing to do with my aim. It could be my release, my head position, my finger tension... But it isn't my aim. With instinctive, I could be holding the point at different spots but I'd never know.
Gap shooting at turkey-sized targets requires more fiddling so maybe put that off for a while. But full-length, heavy arrows can shrink your gaps down to manageable sizes. With full-length arrows, my gap at 20 yards is only about 8-9". I put the tip of the arrow right near the turkey's knees (where the feathers start on his legs) and, assuming I did everything else right, the shaft lands somewhere in the kill zone. Pretty hard to mess that up, though I often manage to find a way. Put a full-length arrow of 600+ grains through any modern recurve or longbow that's 40-50# and you'll probably get similar results. It's horrible on our local 3D courses, though, since most of those shots are over 30 yards. But the 0-20 game is a lot easier with that kind of setup.
