Natalia's 30# lbs recurve bow has only up to about 20 years of effective range, or rather a flat trajectory, which for rabbits and grouse might be plenty good.
I shoot in backyard to practice my form and to work up the strength to shoot my hungarian/mongol 100# bow. I shoot compound bow (65#-85#) to strengten my left hand (lifting and stabilizing my aim) and traditional recurves (45#, 55#, 100#) bow to strengthen my right hand and back muscles.
Natalia has missed Sheltie 6 times in the row! Lucky dog!
