Lmao, I have that same actuator. What do you guys think is an optimal weight for a projectile meant to cause good damage and still acheive good range? Thanks for all the help guys :D

That's not really a question one can answer. If the projectile has good aerodynamics, and sectional density and center of gravity are taken into consideration, it should work well.

Well I did done research, and found that a projectile with the nose cone and body in a 1:1 ratio, with the back edge chamfered in a bit. I might hollow out part if the back to move the center of gravity forward. Is this correct?

Would a chamber 1/2 in diameter , but longer, cause issues with power?

Drop the power, increase the velocity...
