PostSubject: BB weight and velocity   Sun Apr 06, 2008 11:25 pm

What weigh bbs are best with different velocitys. eg. what weight bb has the best range and accuracy for aegs with velocities of 300, 325, 350, 380, and 400fps?

well the fps coincides with the bb being used. Youll have to have a base bb weight, say .2g, and then compare the other weights to that. But a guns shooting 300fps with .2g will always poorer accuracy than a gun shooting 300fps with a .25g, though i cant say how the weight will effect the range.

I think it would be accurate to say that using the highest weighted bb will be the best at any velocity. That is if youre using a gun that has 300fps with .2g bbs it would not have the sam fps when using .25g due to the weight difference. The fps would decrease to something like 280 (i think), and along with that the range would also decrease. But on the other hand the accuracy will increase.

If i do remember correctly i had an old topic about the best bbs, which gave this kind of info... well similar info. I will try to scrounge it up.

In my experience:
Less than 350 fps: .23g
351fps-420fps: .25g
Above 420fps: .28 or .3.

All of this depends on how effective the hop-up is at spinning the heavier bb. If the hop-up won't put enough spin on it, you may need to drop to the next lowest weight in order to get the lost range back.

Also, I've yet to have any gun perform better with a .2g than with a .23g. Sure the FPS is better with the .2, but range and accuracy will pretty much always be better with the .23.

So the heavier the bb the better in both range and accuracy?

not exactly

the heavier the BB, the more accuracy. Since you have better accuracy, it increases the gun's EFFECTIVE range, but it DECREASES the overall range.

I use .25s for my stock E1 G36C and they are MUCH more accurate than .2s. (g36 shoots 350 fps)

I have a mostly stock E1 M733, what bb weight would you recommend: .2's, .23's, or .25's? I am thinking of buying some .23's but other recommendations are welcome.

Get .23s or .25s. Either will work well.

Thanks guys, in that case I'll stick with .23's.

That's why God invented adjustable hop-up....

So then the range won't really be diminished at all so long as you properly adjust your hop up?

It all depends on the gun's/hop-up's quality. In theory it should work that way, but airsoft tech is unfortunately less advanced than some people make it out to be. Truth is, at ranges way out there bb's tend to have a mind of their own due mostly to the fact that an airsoft gun doesnt shoot the same exact way every shot like a well machined real steel would. Factor that in with environmental factors like wind and you have to really know your weapon to make shots count past their effective range. I'll put it like this: you CAN extend (or conserve) your range by turning up the hop when using a heavier BB, but unless you have top of the line buckings and a tightbore, doing so will only help your distance shooting a tad because you'll be "reaching" as I call it. I hate the term "overall range" anyway because it imply's the maximum distance the bb will travel but 99.99 % of the time you'll be getting lucky at that distance and that doesnt really impact the ability of the weapon to engage targets because at "overall" or "max" ranges you'll be giving them a drizzel of pellets as opposed to a shot they can feel and call, which is a waste of effort.
