I shot an old Fred Bear made recurve until a few years ago. It's not hard to do but takes practice. You have to develop a feel for it. I drew and released together. Hard to describe but basically the harder you pull the the weight builds on your fingertips. Then as you reach about what you can draw, let the string slip, but it's all in one motion.
That bow is more of a collectors piece. I retired it and got a compound but am not Robbin' Hood.
