FPS vs BB weight

Wondering which bb to use for maximum accuracy & range in your gun setup?
Here`s a post of proven guide of bb weight for certain fps.

Using suggested bb will result in maximum flat trajectory WITHOUT adjusting hop-up significantly.

FPS on left measured with 0.2

280 fps ~ 0.2g

300 fps ~ 0.2g

325 fps ~ 0.2g

350 fps ~ 0.2g

375 fps ~ 0.2g
                0.25g for longer range

400 fps ~ 0.25g for more impact
                0.2g for higher bb speed

425 fps ~ 0.25g for more impact
                0.2g for higher bb speed ( sometimes 0.2 fly up at over 400 fps)

450 fps ~ 0.25g for decent speed (400-410fps)
                0.28g for more impact but lower fps

475 fps ~ 0.3g balance between speed & impact
                0.36g reach longer range when applying hop-up

500 fps ~ 0.36g need to apply bit of hop up for flat trajectory
                0.4g longer range & impact but at lower speed
