strange fps occurance?

so i have two guns, an m249 and an m16, both are fully upgraded as far as compression goes, cyl head, piston head with #14 o ring, air seal nozzle just everything, the works, both also have prometheus tightbores that are the same length (533mm, 6.03) the m249 (140 spring) shoots about 450 fps and the m16 (stock spring) shoots at about 425 fps, they both have nearly identical internals except for the spring (249 requires a larger spring to shoot same fps) but with .25 the saw shoots around 390-95 and the m16 shoots about 385-90, i am curious if anyone knows why my m249 is dropping 50-60 fps where my m16 is only dropping 40? and also is that normal to drop that much fps?

all results were verified with a chrono with ics .2 and .25 bbs, my chrono does not have a .25 setting so i am a little curious as to if that effects the readings i got from the .25 thank you
