Re: heavier bbs

It doesn't work like that.

Before lots of science posts, what site are you going to? and what is the definition of their dos limits?

Re: heavier bbs

ultimate wargames will let me use my sniper if it fires at 400fps

Re: heavier bbs

I'd be extremely suprised if that figure was to be measured using anything other than 0.2g BBs. You need to modify your gun to lower it's power, not change the weight of the BBs you're using.

Re: heavier bbs

I believe ( and im sure the whole community will confirm ) that it is 400fps with a .2g round.

If your rifle is firing at 486 with a .36 round, that is prob closer to 600fps with a .2.
I dont know of any UK site which allows that.

Re: heavier bbs

486fps on a .36g bb is 652fps with a .2g bb

Re: heavier bbs

ok i will have to clip the spring then might bring it down

Re: heavier bbs

not scientific here but generally 1 coil = approx. 15-20 fps!

dont take this for gospel as different rifles, different springs etc etc can have different tolerances better/worse ariseals etc.

Re: heavier bbs

i will clip then chrono with .2's and keep goin till i get to 400fps. i honestly didnt know i had to chrono with .2's thanks for the info

Re: heavier bbs

spring will be too short if you clip enough coils off to get it that low from that high.
ALWAYS chrono on .2s, adding heavier ammo may travel slower (fps) but hit alot harder (joules).

Re: heavier bbs

get it under 350fps on .2s then use .28s in it, with a tightbore and firefly soft bucking, should be sweet
