550fps with 0.20g will be 450fps using 0.36g BBs (in my M24 with Laylax 170 spring). In all guns I've tested various weights in, there is a 100fps difference between 0.20g and 0.36g BBs. Pretty easy rule of thumb right there, gives you a ballpark velocity if you are using 0.28g (divide by half, ~50fps difference between 0.20g and 0.28g).
