Just to clarify. For each usage of wind pumpkin can nullify Jin's normal projectiles. Pumpkin can also only hit once per use of wind. So if you want to nullify a projectile, run in and still hit/force jin to block pumpkin, you must use another wind. Jin also has a slower moving, larger projectile that will take multiple hits, so trying to nullify it with pumpkin would be a waste of wind. I'm not even sure you can nullify it with pumpkin.
